A-4000 Series Oil Removal and Pressure-Reducing
Stations and Air Compressor Accessories
Product Bulletin Code No. LIT-718060
Issued September 27, 2013
Supersedes September 26, 2007
The A-4000 Series Oil Removal and
Pressure-Reducing Stations (see Figure 1, Figure 2,
Figure 3, and Figure 4) are available in single or dual
PRV models in 10 or 20 scfm (4.7 or 9.4 l/s) maximum
flow capacities. In addition, each unit features a
four-way bypass valve, coalescing and activated
charcoal oil removing filters, and is completely piped
with copper tubing, which reduces friction, allows
higher flow rates, and meets fire codes in mechanical
equipment rooms. The filter combination removes oil
aerosols and vapors to provide clean, oil-free air for
pneumatic control systems. All models provide
maximum performance for a period of 1 year, at which
time the coalescing and activated charcoal filter

models can provide filtered, high-pressure air to
remote PRV stations. All models have a maximum
input pressure rating of 150 psig (1,050 kPa) and an
upper temperature limit of 125°F (52°C).

Remote-Mounted 3/8 in. Pressure-Reducing Station
The A-4000-138 Remote-Mounted 3/8 in. Pressure-Reducing Station (see Figure 7) comes completely assembled
with a wall mounting bracket, 0 to 30 psig gauge, safety relief valve, and 3/8 in. O.D. compression elbow fittings on
the high- and low-pressure sides. The desired output pressure can be easily adjusted between 0 and 30 psig using
the black knob. The factory-set safety relief valve relieves overpressures exceeding 25 psig (175 kPa). Pressure
adjustments up to 50 psig (350 kPa) can be made; however, the 0 to 30 psig gauge must be replaced with one
having a higher scale, and the safety relief valve must be readjusted to the required higher value. Designed to
handle input pressures up to 300 psig (2,100 kPa) at air flows exceeding 20 scfm (9.4 l/s), this pressure-reducing
station regulates an output pressure within a 0.2 psi (1.4 kPa) variation with a 20 psi (140 kPa) variation in input
pressure.

Servicing Procedure for Coalescing Filters
All coalescing filters are equipped with an automatic
drain from which accumulations of entrapped liquids
are automatically blown out. The filter element should
be replaced when the leaving air pressure gauge
(mounted on the PRV station charcoal filter head)
indicates less than 50 psig (350 kPa) the differential
pressure between the leaving and input gauges is
15 psi (105 kPa) or more, or after one year of service—

Intake Air Filter
The dry-type intake air filters (see Figure 17) are rated
99% efficient at a 10 micron rating, regardless of air
demands or temperature variations. A steel housing
with baked enamel finish makes these filters suitable
for either outside or inside locations.
