moisture removal and temperature variation demands on the refrigerated dryer.

Between the compressed air receiver and dryer, a general purpose coalescing filter with

an automatic drain is used to remove liquid water, liquid oil and solid particles from the

airstream. Pre-filtering eases the load on the dryer and prevents an emulsion of water,

oil and particulates from forming. This emulsion can leave a deposit that reduces heat

exchanger efficiency and clogs automatic drains.

For applications that require ultra-clean air, additional filtering may be required to

remove the oil aerosols and vapors present in most systems. Oil coalescing filters

remove oil in aerosol form. To remove oil vapor from the air stream use a filter fitted

with an adsorbing activated carbon cartridge at the dryer outlet.

Note that the inlet and outlet ports of the air dryer are labeled. A dryer bypass valve

should be installed for air dryer servicing. If the aftercooler exit air temperature

averages less than 100°F, the dryer including prefilter and bypass system can be

placed between the aftercooler separator and receiver.

If not already in place, connect condensate drain tube to the dryer's moisture separator

drain trap. Position outlet of drain tube in such a manner that condensate will be

drained away from dryer and other mechanical or electric equipment.

Make sure when piping is in place that no undue stress is placed on dryer connections.

Union joints or flexible connections are recommended to relieve stress.

Dryer is to be connected to an appropriate electrical power source based upon

specifications shown on unit data label. Do not connect unit to a power source other

than that called out on data label. Power source should incorporate a fused disconnect

using a fuse, not exceeding the maximum fuse size stated on the dryer data label.

Piping:

A. Piping installation should follow general air line piping procedures.

B. A bypass valve system is recommended in the dryer's pipe connections. This

permits servicing of the dryer without the interruption of the airflow.

C. If the pipes connecting the dryer vibrate, such as from compressor vibration, use

vibration absorbers so that the dryer is not damaged over time by the vibration.

D. The inlet and outlet ports on the dryer are labeled.

E. Direct the drain tube under the dryer to a suitable sump. Do not restrict the drain.

Filtration:

A. A compressed air filter with automatic drain should be installed upstream of the

dryer. Filtration of dirt, rust and liquids from the supply air will greatly enhance the

performance and life of the dryer. Your distributor can provide additional information on

compressed air filters.
