fficiency and safety are the primary concerns when selecting components for compressed air systems. Products of
E
inferior quality can not only hinder the performance of the unit, but could cause system failures or bodily harm. Select only top
quality components for your system. Call your local ROLAIR
DRIVE PULLEYS: Drive pulleys must be properly aligned and drive-belt
tension set to specifications. Improper pulley alignment and belt tension
can cause motor overloading, excessive vibration and premature belt
and/or bearing failure.
GUARDS: All mechanical action or motion is hazardous in varying
degrees and needs to be guarded. Guards should be designed to
achieve the required degree of protection and still allow full air flow
from the compressor flywheel across the unit. Guards shall be in
compliance with O.S.H.A. safety and health standards and any state or
local codes. When the compressor is installed, make sure guard side is at least 18" away from the wall to provide adequate cooling
of motor and pump.
CHECK VALVES: Check valves are designed to prevent back-flow of air pressure in the compressed air system (air flows freely in
one direction only.) The check valve must be properly sized for air flow and temperature. Do not rely upon a check valve to isolate a
compressor from a pressurized tank or compressed air delivery system during maintenance procedures!
MANUAL SHUT-OFF VALVES: Manual shut-off valves block the flow of air pressure in either direction. This type of valve can be
used to isolate a compressor from a pressurized system, provided the system is equipped with a safety-relief valve capable of being
manually released. The safety-relief valve should be installed between the manual shut-off valve and the compressor.
SAFETY-RELIEF VALVES: Safety-relief valves aid in preventing system failures by relieving system pressure when compressed air
reaches a determined level. A check valve and safety relief valve are required in all compressed air systems. Safety-relief valves are
pre-set by the manufacturer and under no circumstances should the setting be changed.
PRESSURE SWITCHES: The pressure switch detects the demand for compressed air and allows the motor to start. When the
demand is satisfied, the unit stops and unloads the head pressure with a short hissing noise. Engine-driven units use a pilot valve
instead of a pressure switch. It will discharge compressed air to atmosphere or open the intake valve upon reaching a
predetermined pressure setting.
PRESSURE VESSELS: ASME coded pressure vessels must not be modified, welded, repaired, reworked or subjected to operating
conditions outside the nameplate ratings. Such actions will negate code status.
DUTY CYCLE: All ROLAIR
belt-driven air compressors are equipped with S1 or 100% duty cycle motors and pumps. Given proper

operation. However, an excessive amount of starts per hour may generate enough heat to trip the motor overload. Please contact
our factory Customer Service Department if overload problems repeatedly occur.
Several ROLAIR
direct-drive machines, Models FC1500HBP2, FC1500HS3 and JC10, are rated for 70% duty cycle. If
®
subjected to continuous operation the internal overload will shut down the motor and only restart when sufficient cooling has
occurred.
HIGH-ALTITUDE OPERATION: Due to a decrease in atmospheric pressure air compressor pumps produce less CFM at higher
elevations. As a rule of thumb the output will decrease approximately three percent per 1000 feet of elevation. Also, because air at
higher elevations is less dense and does not cool as well, electric motors cannot be subjected to the full nameplate service factor
amp rating and may need to be upgraded to avoid repeated overheating.
Direct drive or hand-carry compressors built with cold-start valves may need to be modified when operated in higher
elevations. Carburetors on gas-powered air compressors may also need to be rejetted to perform properly at higher elevations.
Contact our factory Customer Service Department if your normally reliable air compressor fails to operate correctly at higher
elevations.
