A35 EXAM fully solved & updated (latest version verified for accuracy)
(Questions + Answers) Solved 100% Correct!!
Air compressors power... - (ANSWER)(1) industrial equipment and (2) construction tools
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 force it into a container UNDER
PRESSURE. The more air forced into the container, the greater the pressure. Compressed air can be
discharged from the container at a controlled rate.
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

(Questions + Answers) Solved 100% Correct!!
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 air receiver tank may be turned and stood on end w/
the air compressor bolted to the top of the tank.
Power to air compressor - (ANSWER)entire unit is driven by an electric motor. Motor activates a series of
drive belts. Belts power the moving parts of the unit--like w/ power steering and alternator in
automobile
Compression Chamber operation - (ANSWER)Air is compressed in compression chamber which consists
of a PISTON inside a CYLINDER. Piston moves up and down.
When piston moves down -->draws air into cylinder, through INTAKE VALVE (valve automatically opens
when piston moves down).
When piston moves up-->air is compressed (intake vale automatically closes to avoid air escaping from
cylinder).
Air Reciever Operation - (ANSWER)When air pressure reaches a certain level, it forces open a DISCHARGE
VALVE (which is spring loaded). This releases compressed air into air reciever (aka air tank), which is what
supplies compressed air when needed.
Single Stage Air Compressor - (ANSWER)with one cylinder and one piston
Multi Stage Air Compressor - (ANSWER)with more than one piston and cylinder.
