SAFETY

1.1 GENERAL

Sullair Corporation and its subsidiaries design and

manufacture all of their products so they can be

operated safely. However, the responsibility for safe

operation rests with those who use and maintain

these products. The following safety precautions are

offered as a guide which, if conscientiously followed,

will minimize the possibility of accidents throughout

the useful life of this equipment.

The compressor should be operated only by those

who have been trained and delegated to do so, and

who have read and understood this Operator's

Manual. Failure to follow the instructions, procedures

and safety precautions in this manual may result in

accidents and injuries. NEVER start the compressor

unless it is safe to do so. DO NOT attempt to operate

the compressor with a known unsafe condition. Tag

the compressor and render it inoperative by

disconnecting and locking out all power at source or

otherwise disabling its prime mover so others who

may not know of the unsafe condition cannot attempt

to operate it until the condition is corrected.

Install, use and operate the compressor only in full

compliance with all pertinent OSHA regulations and/

or any applicable Federal, State, and Local codes,

standards and regulations. DO NOT modify the

compressor and/or controls in any way except with

written factory approval.

While not specifically applicable to all types of

compressors with all types of prime movers, most of

the precautionary statements contained herein are

applicable to most compressors and the concepts

behind these statements are generally applicable to

all compressors.

1.2 PERSONAL PROTECTIVE

EQUIPMENT

A. Prior to installing or operating the compressor,

owners, employers and users should become

familiar with, and comply with, all applicable

OSHA regulations and/or any applicable Federal,

State and Local codes, standards, and regula-

tions relative to personal protective equipment,

such as eye and face protective equipment,

respiratory protective equipment, equipment

intended to protect the extremities, protective

clothing, protective shields and barriers and elec-

trical protective equipment, as well as noise

exposure administrative and/or engineering con-

trols and/or personal hearing protective equip-

ment.

1.3 PRESSURE RELEASE

A. Install an appropriate flow-limiting valve between

the service air outlet and the shut-off (throttle)

valve, either at the compressor or at any other

point along the air line, when an air hose exceed-

ing 1/2" (13mm) inside diameter is to be con-

nected to the shut-off (throttle) valve, to reduce

pressure in case of hose failure, per OSHA Stan-

dard 29 CFR 1926.302(b)(7) and/or any applica-

ble Federal, State and Local codes, standards

and regulations.

B. When the hose is to be used to supply a mani-

fold, install an additional appropriate flow-limiting

valve between the manifold and each air hose

exceeding 1/2" (13mm) inside diameter that is to

be connected to the manifold to reduce pressure

in case of hose failure.

C. Provide an appropriate flow-limiting valve at the

beginning of each additional 75 feet (23m) of

hose in runs of air hose exceeding 1/2" (13mm)

NOTE

1.9 LIFTING

A. If the compressor is provided with a lifting bail,

then lift by the bail provided. If no bail is provided,

then lift by sling. Compressors to be air-lifted by

helicopter must not be supported by the lifting

bail but by slings instead. In any event, lift and/or

handle only in full compliance with OSHA stan-

dards 29 CFR 1910 subpart N and/or any appli-

cable Federal, State, and Local codes, standards

and regulations.

B. Inspect points of attachment for cracked welds

and for cracked, bent, corroded or otherwise

degraded members and for loose bolts or nuts

prior to lifting.

C. Make sure entire lifting, rigging and supporting

structure has been inspected, is in good condi-

tion and has a rated capacity of at least the

weight of the compressor. If you are unsure of

the weight, then weigh compressor before lifting.

or swinging of the compressor once it has been

lifted clear of the ground.

F. DO NOT attempt to lift in high winds.

G. Keep all personnel out from under and away

from the compressor whenever it is suspended.

H. Lift compressor no higher than necessary.

DANGER

All field equipment must be tested for elec-

trostatic fields prior to servicing or making

contact with the machine using the follow-

ing or equivalent test equipment:

• 90-600 VAC: Volt detector such as

Fluke Model 1AC-A

• 600-7000 VAC: Voltage detector

such as Fluke Networks Model

C9970

It is the responsibility of each organization

to provide/arrange training for all their

associates expected to test for electrostatic

fields.

SECTION 1

I. Keep lift operator in constant attendance when-

ever compressor is suspended.

J. Set compressor down only on a level surface

capable of safely supporting at least its weight

and its loading unit.

K. When moving the compressor by forklift truck,

utilize fork pockets if provided. Otherwise, utilize

are provided, then make sure compressor is

secure and well balanced on forks before

attempting to raise or transport it any significant

distance.

L. Make sure forklift truck forks are fully engaged

and tipped back prior to lifting or transporting the

compressor.

M. Forklift no higher than necessary to clear obsta-

cles at floor level and transport and corner at

minimum practical speeds.

N. Make sure pallet-mounted compressors are

firmly bolted or otherwise secured to the pallet

prior to attempting to forklift or transport them.

NEVER attempt to forklift a compressor that is

not secured to its pallet, as uneven floors or sud-

den stops may cause the compressor to tumble

off, possibly causing serious injury or property

damage in the process.

1.10 ENTRAPMENT

A. If the compressor enclosure, if any, is large

enough to hold a man and if it is necessary to

enter it to perform service adjustments, inform

other personnel before doing so, or else secure

and tag the access door in the open position to

avoid the possibility of others closing and possi-

bly latching the door with personnel inside.

B. Make sure all personnel are out of compressor

before closing and latching enclosure doors.

ES-6 USER MANUAL

DESCRIPTION

2.1 INTRODUCTION

Your new Sullair flood-lubricated rotary screw air

compressor will provide you with improved reliability

and greatly reduced maintenance.

Compared to other types of compressors, the Sullair

rotary screw is unique in mechanical reliability, with

"no wear" and "no inspection" required of the working

parts within the compressor unit.

Read Section 6: Maintenance to keep your

compressor in top operating condition. Should any

questions arise which cannot be answered in the

following text, call your nearest Sullair office or the

Sullair Corporation Service Department.

2.2 DESCRIPTION OF

COMPONENTS

Refer to Figure 2-1. The components and

assemblies of the ES-6 Series air compressor are

clearly shown. The complete compressor consists of

an encapsulated compressor system, inlet system,

cooling system and control system.

The compact design of the ES-6 Series air

compressor provides easy access to all serviceable

components.

2.3 ENCAPSULATED

COMPRESSOR SYSTEM,

FUNCTIONAL DESCRIPTION

Refer to Figure 2-2. The encapsulated compressor

includes compressor unit, fluid management system,

and motor section. The Sullair compressor unit is a

single-stage positive displacement lubricated type

compressor. This unit is equipped with tapered roller

bearings on the discharge, and cylindrical roller

bearings on the inlet end for high load carrying

capacity. This unit provides continuous pulse-free air

compression to meet your needs. With a Sullair

compressor there will be no maintenance or internal

inspection of the compressor

Fluid is injected into the compressor unit in large

quantities and mixes directly with the air as the rotors

turn, compressing the air. The fluid flow has three

main functions:

1. As coolant, it controls the rise of air tempera-

ture normally associated with the heat of

compression.

2. It seals the leakage paths between the rotors

and the stator and also between the rotors

themselves.

3. It acts as a lubricating film between the

rotors allowing one rotor to directly drive the

other, which is an idler.

The air/fluid mixture discharges directly into the fluid

management system.

The fluid cooler bypass valve helps assure proper

cooling by directing the fluid to the fluid cooler when

discharge temperature reaches the thermostat

temperature setting.

During start-up in cool ambient conditions, the cooler

pressure drop will cause the filter bypass valve to

open up, assuring adequate fluid supply to the

compressor.

All fluid entering the compressor unit passes through

WARNING

DO NOT remove caps, plugs and/or other

components when compressor is running

or pressurized. Stop compressor and

relieve all internal pressure before doing so.

ES-6 USER MANUAL SECTION 2

the replaceable fluid filter element. This replaceable

filter element contains a built-in bypass valve. Under

conditions of restricted flow through the element, the

bypass valve helps ensure adequate compressor

fluid flow, as well as helps prevent element failure.

LUID MANAGEMENT SYSTEM

The fluid management system consists of a

multichambered primary/secondary separator, the

final air/fluid separator element, cooler bypass group

and fluid filter.

As compressed air/fluid enters the sump, the first

fluid separation takes place due to a reduction of flow

speed coupled with a change of direction of the flow

within the sump housing. Then the compressed air

reaches the separator, where the finest fluid drops

and mist are separated.

OTOR/DRIVE SECTION

The motor/drive section consists of a squirrel cage

induction motor and integrated drive gearing which is

separated from the motor by a replaceable shaft

seal.

The minimum pressure/discharge check valve is

mounted on the compressor drive housing. Its

functions are as follows:

1. Maintain a minimum sump pressure of 60

psig (4.1 bar) under full load operation to

help assure adequate fluid pressure.

2. Act as a check valve to isolate the compres-

sor from the system at shutdown or unload.

2.4 COMPRESSOR COOLING

SYSTEM FUNCTIONAL

DESCRIPTION

The compressor cooling system consists of a fluid

cooler, fan and cooler shroud.

The fan is mounted on the motor's shaft end opposite

the compressor. Air is drawn over the motor as well

as through the cooler. The air provides motor cooling

and removes compression heat from the fluid.

2.5 AIR INLET SYSTEM,

FUNCTIONAL DESCRIPTION

The compressor inlet system consists of a dry-type

air filter and an air control valve. Reacting on a

pressure signal, the valve closes the intake for

unloaded operation. The valve also acts as a check

valve upon shutdown.

2.6 CONTROL SYSTEM,

FUNCTIONAL DESCRIPTION

The purpose of the compressor control system is to

maintain compressor capacity to meet the system

demand.

It consists of an inlet valve, pressure regulator valve,

solenoid valve, control lines and the motor start

selector switch.

The selector switch has three settings: MANUAL/

START, OFF/RESET and AUTOMATIC START/

STOP.

ANUAL MODE

In the manual mode the ball valve should be closed

to isolate the pressure regulator. The compressor

motor will start and the air control solenoid will be

energized (closed.) During this time the inlet valve is

fully open due to inlet air flow, and the compressor

will start to deliver compressed air. When the air

demand is less than the rated flow for the

compressor, the service line pressure will rise to the

pressure switch cut-out setting. The system pressure

switch opens, interrupting the electrical power to the

solenoid valve. The solenoid valve opens allowing

pressure to be applied to the inlet valve causing the

inlet valve to fully close. The compressor will

continue to run (unloaded) until the line pressure

drops to the low setting of the pressure switch--the

pressure switch closes, reenergizing the normally

open solenoid valve and allows the compressor to

load again.

ANUAL MODULATION CONTROL MODE

In the modulation control mode the ball valve should

be open to allow pressure to the pressure regulator.

The compressor motor will start and the system

pressure will rise until it reaches the set point of the

pressure regulator. The pressure regulator will them

begin to open allowing pressure to be applied to the

inlet valve. The pressure regulator will modulate the

inlet valve to match system demand.

FF/RESET MODE

The compressor motor, if running, will stop if the off/

reset position is selected. If the compressor during

normal running has a fault caused by either overload

or high discharge temperature, the compressor will

stop. After a fault has been cleared, the compressor

can not be restarted unless the Off/Reset mode is

selected on the selector switch, prior starting in any

other mode of operation.

UTOMATIC MODE

In the automatic mode of operation, the compressor

operates the same as in the manual mode except

that when the pressure switch unloads the machine

the compressor motor will stop. The motor will

automatically restart when the line pressure drops to

below the set-point of the air pressure switch. If the

compressor is equipped with a wye-delta starter, the

compressor will not restart until the compressor

sump pressure drops to the minimum set-point on

the sump pressure switch. It is not recommended to

open the pressure regulator ball valve for the

automatic mode of operation.

2.7 INSTRUMENTATION,

FUNCTIONAL DESCRIPTION

Due to the simplicity of the ES-6 Series compressor,

the only instrumentation necessary is a line pressure

gauge which is located on the left side of the

electrical control center and a discharge temperature

gauge which is located on the right side of the

electrical control center. The line pressure gauge

reads plant air system pressure only.

NOTE

At compressor shutdown, the sump pres-

sure is released to atmosphere through

the solenoid valve. The line pressure

gauge will continue to read system pres-

sure.
