PneumaticPlus SAU4020M-N04G Compressed Air Filter Regulator Modular Combo 1/2" NPT - Manual Drain, Poly Bowl

Installation Install units so the airflow is in the direction "IN-OUT" as indicated by arrow on the head of the unit. Install filter first in line of additional units such as regulators or lubricators, and as close as possible to the pneumatic tools or appliances being serviced. Unit must be installed in parallel from floor, downstream position for proper function. Do not install polycarbonate bowl in pressure that exceeds 150 PSI or where there is a presence of solvents harmful to polycarbonate. In these cases, use a metal bowl. The Unit can dis-assemble or assemble using a Phillips-head screwdriver or Allen wrench. An insert feature allows simple installation and removal in any location without disturbing the existing piping arrangement. The regulator can be mounted in either up or down position. This unique design allows unlimited adaptation to air preparation systems. Unit will permit use of standard size pipe nipples. Operation & Adjustments Filtering out of dirt and foreign particles, and the separation of moisture is automatic with air flow. There are no moving parts and no adjustments are necessary. Accumulated sludge and moisture should be drained off. Sediment should not be permitted to fill above the lower baffle. Wash filter element at intervals with methylene chloride or similar cleansing fluid to maintain filtering efficiency. To clean element, depressurize system, unscrew polycarbonate bowl and unscrew element from head. Dry filter element thoroughly before reassembling. Clean filter bowl(s) only with soapy water. Inspect O-ring, replacing if damaged or distorted. Reassemble with care to avoid stripping threads on bowl. After a metal bowl with sight is tightened, it may be rotated up to 180 (for proper viewing.) Before supplying the air, turn the adjusting knob counter-clockwise until compression is released from the control spring. Turn on the air supply and adjust the knob to set the desired secondary pressure by turning the knob clockwise.
