and Answers 2025 | The Ultimate Guide
for Yr. (2026/2027)
Questions covered on this Topics
Compressor operation: How a compressor works, the
function of the motor, drive belts, and compression
chamber.
Safety: The function of safety valves, importance of
raising compressors above ground, and proper procedures
for starting compressors.
Maintenance: Regular checks of the cooling system,
oil level, and draining the air receiver.
Component functions: The role of components like the
unloading valve, check valve, automatic control device,
pressure gauge, and filter and moisture separator.
Types of compressors and cooling: Differences
between small (air-cooled) and large (water-cooled)

Quiz_________________?
Air compressors are sometimes called -
Answer✅
air pumps
Quiz_________________?
Air compressors can be powered by: -
, Answer✅
(1) electric motors;
(2) internal combustion engines; or
(3) steam turbines
Quiz_________________?
Air compressors enable... -
Answer✅
(1) efficient repair of all types of vehicles; and (2) facilitate their
safe operation on public thoroughfares
Quiz_________________?
Air compressors power... -
Answer✅
(1) industrial equipment and (2) construction tools
Quiz_________________?
Air intake valve -
Answer✅
safety component.
Fitted w/ an air filter which prevents dust from being drawn into
compression cylinder. Dust in the compressor could result in fire
in the cylinder b/c of heat in the cylinder. Fire could case damage
to air compressor.
, This is why its important to make sure filter is always clean and
securely connected to the compressor.
Quiz_________________?
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.
Quiz_________________?
As air is compressed it becomes -
Answer✅
heated.
This is why in a multi stage air compressor there is an intercooler
between stages of compressor.
Quiz_________________?
Automatic Control Device -
Answer✅
Attached to receiver.
