SOLUTIONS
◉ Examples of equipment powered by air compressor Answer:
pneumatic wrenches, lifts in auto service stations, paint spray
booths
◉ Air compressors enable... Answer: (1) efficient repair of all types
of vehicles; and (2) facilitate their safe operation on public
thoroughfares
◉ Permit is required for air compressor Answer: that compresses
air above 100 PSI
◉ Types of air compressors Answer: (1) reciprocating;
(2) centrifugal;
(3) solar; and
(4) rotary
*Difference is the way in which they compress air
, ◉ How do air compressors work Answer: take the air in a room and

◉ Most common air compressor Answer: Reciprocating
◉ Air compressors are sometimes called Answer: air pumps
◉ Air compressors can be powered by: Answer: (1) electric motors;
(2) internal combustion engines; or
(3) steam turbines
◉ Explosions & air compressors Answer: If there is a build up of
flammable gases (ex: in service stations and workshops), those
gases are heavier than air and fall to the floor before spreading
outward. These gases are easily ignited by sparks and high
temperatures--which INCLUDES the heat generated by an air
compressor.
◉ To avoid explosions w/ air compressors Answer: Raise air
compressor at LEAST 5 feet above ground level so that no flammable
gases are drawn into the compressor. To meet the height
requirement you can place compressor on a shelf or bench OR the
