INSTALLATION AND MAINTENANCE

GENERAL

The components of the air treatment system are coupled for left-to-right flow (as in

symbolic representation). The air flow is indicated by an arrow on the front.

A right-to-left flow set-up can be obtained by turning the components through 180°

and moving the pressure gauge and bowl protections to face forwards.

MOUNTING

(3) Modulair 107, 2 mounting holes of diameter 4.1 depth C4: 38 / Modulair 112, 2 mounting holes of dia. 5.5 depth C4: 47.5

NOTE - The regulator or filter/regulator can also be secured with a top bracket and ring (accessories)

- The regulator can be panel-mounted separately using a mounting ring (accessory)

Components of the "MODULAIR 107 or 112" can

easily be assembled with the connection fitting

(1) which is accessible from the front.

ASSEMBLY OF COMPONENTS

The standard systems consist of a self-contained filter/regulator and

a lubricator. This configuration offers a gain in the space required

of 30% compared combining three separate components. However,

if the user wishes to constitute a system with an independent filter

and regulator, the components can be procured separately together

with two assembly kits.

Standard system

consisting of 2 elements

with self-contained filter/regulator

and lubricator

System consisting of

3 components (procure

2 assembly kits in addition)

Air service equipment of the Modulair 107 and 112 range exists in versions

intended for use in potentially explosive atmospheres caused by gases,

vapours, mists an/or dusts (ATEX directive 94/9/EC). Startup and maintenance

are to be performed as detailed below.

INSTALLATION AND MAINTENANCE

FRL AIR TREATMENT SYSTEM

Refer to the specifications of the system component.

INSTALLATION

●●

●

Place after isolation valve and before lubricator

●●

●

Position vertically (maximum inclination 5°)

●●

●

Installation accessories (on request) :

- top bracket and ring (for separate component)

- side brackets

●●

●

Pressure and temperature: see general specifications

other specifications: see filter and regulator

MAINTENANCE (see filter and regulator)

FILTER

INSTALLATION

●●

●

Place near point of use, after isolation valve

●●

●

Position vertically (maximum inclination 5°)

●●

●

Pressure and temperature: see general specifications

●●

●

Visual condensate level check:

- through transparent bowl (polycarbonate bowl version)

- through small window in front of bowl protection

●●

●

Depending on the version selected: the filter is equipped with:

- A semi-automatic drain (G 1/8 connection)

Drain closes on bowl pressurization

Opens when depressurized

Can be operated manually by pressing plunger when bowl is

under pressure

- Automatic drain - operating pressure 2 to 10 bar (for Modulair 112)

(nipple connection for Ø 6 ID hose)

Drain opens by built-in float when maximum condensate level

is reached

Recloses after discharging condensates

Can be operated manually (knurled knob)

- Manual drain

MAINTENANCE
