Installation Considerations

Prior to installing the system, consider the following factors:

• For proper operation, VMAC’s Hydraulic Driven Air Compressor Systems require

proper hydraulic pressure and flow, ensure the hydraulic circuit is designed

with these requirements in mind (see page 17).

• See "Hydraulic Fluid and Line Sizing Recommendations" on page 19 for

additional hydraulic circuit recommendations.

• Is the intended location convenient for electrical, hydraulic, and air

connections?

• Will the intended location require extensive plumbing for the hydraulic system

or air hoses?

• Are the wire lengths, and air/hydraulic hose lengths as short as possible, and

with the least amount of 90° fittings possible?

• Can the oil level at the sight glass be checked easily?

• Can the unit be serviced easily?

• Will there be adequate clearance around the unit to provide good air

circulation and effective cooling (see page 14)?

• Will the unit be protected from excessive exposure to the elements?

• Will the unit be protected from incidental damage from other operations?

• Will the unit be mounted away from heat sources such as engines, exhaust, or

other components that can generate heat.

• Will the unit be mounted where it will be exposed to high contamination levels,

including combustible gases?

• If the intended mounting location is constructed of thin gauge material,

consider using the VMAC Mounting Brackets (P/N: A700140).

The information in this section is critical to ensure proper operation

of the system. Read these requirements prior to beginning the

installation.

Failure to adhere to these recommendations will cause the Hydraulic

Driven Air Compressor system to operate erratically.

The integrated cooler on the Hydraulic Driven Air Compressor

system is capable of removing all of the heat generated during air

compression from the compressor oil and hydraulic fluid.

Additional hydraulic oil cooling (such as VMAC’s Hydraulic Oil Cooler

(P/N: A850001) may be required for any other hydraulic equipment

is installed on the same circuit.

14

Enclosed mounting is not recommended due to the significant heat

generated by the Hydraulic Driven Air Compressor.

While it is not possible to make absolute recommendations regarding ventilation

due to the widely differing circumstances that are possible, duty cycle, ambient

temperature and enclosure shape are some of the important variables that must be

considered.

Top Mounting

“Top mounted” is the preferred mounting location for the Hydraulic Driven Air

Compressor. Placing the unit on top of the service body provides the best access to

cool fresh air. Maintain a minimum of 6 in between the sides of the Hydraulic Driven

Air Compressor and all other solid objects (Figure 1).

Mounting Locations and Ventilation

Mounting the Hydraulic Driven Air Compressor in an enclosure will limit access

to cool fresh air, restrict the escape of hot air from around the unit and have an

adverse effect on cooling which may reduce the unit’s duty cycle. Ensure adequate

ventilation is provided for cooling and to evacuate the heat generated by the unit.

If mounting in an enclosure, VMAC strongly recommends mounting the unit on a

pullout drawer and extending the drawer any time the unit is run.

Figure 1 — Mounting locations

Enclosure mounted

(not recommended)

Top mounted

(Preferred)

Not recommended

VMAC does not recommend mounting the unit at the back of the

vehicle as the drag created when the vehicle is moving causes debris

to be deposited (and accumulated) inside the unit.

Significant ventilation and additional cooling will be required if the

Hydraulic Driven Air Compressor is mounted in the same enclosure

as the hydraulic oil reservoir. The heat generated during operation

will continue to heat the hydraulic fluid (even with fresh ambient air

entering the cooler).

Speed Control

The Hydraulic Driven Air Compressor has the ability to signal for a higher engine

speed under high air demand conditions and for a lower engine speed under low

air demand conditions. A built in, electrically activated idle up system or an after-

market product is required to provide 2 speed operation.

The Hydraulic Driven Air Compressor is capable of constant operation at a fixed

engine speed and hydraulic pump gpm. There are several advantages to configuring

the system for 2 speed operation:

• Lower fuel consumption.

• Lower noise when air demand is low.

• Lower wear rates on the engine, hydraulic pump and compressor.

• Faster warm up during cold start weather.

The preferred approach for speed control is to restrict the hydraulic flow to the

Hydraulic Driven Air Compressor to the minimum requirement for the system

(8 – 9 gpm), this is desirable for cold climate start-up as it keeps hydraulic pressure

low during warm up.

The system must be at, or above, the minimum hydraulic flow before

starting the Hydraulic Driven Air Compressor.

Single Speed Operation (See Figure 3 on page 17 for “gpm vs cfm” chart)

When the system is activated, the Control Box in the Hydraulic Driven Air

Compressor will signal the PTO to increase hydraulic flow to provide the desired

cfm.

2 Speed Operation (See Figure 3 on page 17 for “gpm vs cfm” chart)

When the system is enabled, “Speed 1” is activated and the Control Box in the

Hydraulic Driven Air Compressor will signal the PTO to set hydraulic flow to the

minimum desired cfm.

“Speed 2” is activated to signal the PTO to increase hydraulic flow to provide the

maximum cfm (or speed system warm up).

Hydraulic Requirements

While in operation, the required system pressure will vary between 1,500 psi and

2,800 psi.

The load sensing pressure compensated hydraulic pump must be rated for 3,000 psi

(maximum continuous) and 3,800 psi (maximum) to allow for an additional 200 psi

pressure drop in the pressure lines (external to the system) during startup with cold

hydraulic fluid.

H400011

The system must maintain hydraulic flow between 9 gpm and 14 gpm (Figure 3).

H600011

The system must maintain hydraulic flow between 14 gpm and 21 gpm (Figure 3).

Figure 3 — cfm vs gpm

VMAC is unable to provide hydraulic circuit designs or consult on

specific hydraulic installations. We recommend working with a local

hydraulic expert to design and/or install the hydraulic circuit that

will power the Hydraulic Driven Air Compressor system.

This VMAC Hydraulic Driven Air Compressor is designed to be driven

by a load sensing pressure compensated variable displacement

hydraulic pump.

18

The stated hydraulic flow rates are nominal values only and may change due to

variations in hydraulic system efficiency, load, and flow. Tests should be performed to

confirm that the desired cfm has been achieved.

If the Hydraulic Driven Air Compressor system is being installed into an existing

hydraulic circuit, ensure the circuit meets the requirements listed in this chapter.

See "Hydraulic Fluid and Line Sizing Recommendations" on page 19 for additional

information.

An independent hydraulic system is recommended to simplify

installation, operation, and troubleshooting of the Hydraulic Driven

Air Compressor system.

If this system is being installed in a shared hydraulic circuit, the use

of a shut off valve is advised.
