1 Combination service unit

Combination service unit, i.e. filter/water trap ུ ,

pressure regulator ᆰ and oil mist lubricator ཱུ combined

in one unit.

Mounting

Can be mounted by means of the already fitted mounting

bracket ི or into a rigid line system.

Installation

The combination service unit should always be installed

with the reservoir vertically at the bottom. When

connecting, pay attention to the direction of flow which is

identified on the top of the unit by an arrow ཱ .

Pressure regulator

The pressure gauge ཱི can also be screwed into the back

of the pressure regulator with a specially-shaped seal.

The unused pressure gauge connection should be sealed.

Before initial operation check, the setting knob ཷ is

unlocked ླྀ and the compression spring is fully relaxed by

turning to the left. With pressure pre-sent on the primary

side, the setting knob is now turned to the right until the

pressure gauge indicates the desired secondary pressure.

Subsequent locking ཹ of the setting knob holds the

pressure setting constant.

2 Filter with water trap

Draining the condensate

Manuel:

The collected condensate should be drained regularly and

promptly by turning the manual drain screw ོ to the left.

Fully automatic:

The fully automatic drain valve is open when exhausted.

The valve ཾ closes when a pressure of > 2 bar is present

and there is an air flow of > 160 l/min. If the condensate

level rises so far that the float ཽ is raised, the valve is

briefly opened and the collected condensate is drained to

a certain level. Manual draining of condensate is possible

by turning the knurled screw ཿ to the left. The collected

condensate can be caught by means of a sleeve LW 4.

Cleaning the sintered bronze filter

cartridge

After removing the reservoir, the filter cartridge ེ is

removed by unscrewing the baffle plate ཻ . The filter

cartridge should be washed out with benzine or kerosene

and should then be blown dry from inside to outside. If

heavily fouled, the filter cartridge should be replaced.

3 Oil mist lubricator

A minimum flowrate as per graph ྲྀ is required for

the operation of the oil mist lubricator.

Topping off with oil is possible during operation by

means of an oil spray gun at the opening of the unscrewed

oil filler screw ྂ .

Oil grade:

AVENTICS Pneumatic oil

Part No.1 829 990 046 - 1 l or an oil obtainable from all

petroleum companies corresponding to

HL 25 DIN 51524 – ISO VG 32

Setting the number of drops

The quantity of oil added to the compressed air is set by

means of the metering screw ྀ . Turning to the right

means fewer drops; turning to the left means more drops.

The drops can be seen falling in the sight glass ཱྀ .

Guide value für oil metering:

At 1,000 l/min air flow approx. 1–2 drops/min should fall.

Cleaning the reservoir

At zero pressure, the flange ྃ is loosened and the plastic

reservoir (with or without protective basket) is removed.

To clean the plastic reservoir, use only water, kerosene or

benzine.

Cleaning agents containing tri, such as benzene, acetone,

and all liquids containing softeners, must not be used.
