Medical Gas And Compressed Air

Front 1

Pressure tests

Back 1

Must be performed using oil free dry air or oil free nitrogen and all piping shall be pressurized to 1030 kPa (150 psi) or 1 1/2 times the operating system, whichever is greater. Vacuum lines are tested to a maximum of 415 kPa (60 psi)

Front 2

Atmospheric pressure

Back 2

a term that relates the weight of the air to a particular area on the earths surface

Front 3

Standard air

Back 3

Considered to be air at a temperature of 68 degrees Fahrenheit, atmospheric pressure of 14.7 psi, and a relative humidity of 36%

Front 4

Single stage pump

Back 4

Brings the air from atmospheric to maximum pressure in a single stroke of the piston. They can produce a maximum of 125 psi

Front 5

Two stage pump

Back 5

Two cylinders/ pistons consist of one large piston and one small one

Front 6

Flexible connector

Back 6

should be used in the air line directly down- stream from the unit

Front 7

loop style system

Back 7

the air compressor keep the pressure equalized throughout the whole system. This is very critical in large systems or where any point of use is more than 100 feet away from the compressor

Front 8

Compressed air systems (pneumatic systems)

Back 8

operates above atmospheric pressure and are used as a source of energy to drive numerous types of equipment

Front 9

Air

Back 9

is used for the operation of tools, machinery, motors, dampers, valves, spray painting, medical services, and many other applications

Front 10

Air receiver tank

Back 10

They must hold an adequate air supply to prevent the system from a pressure drop of more than 5 psi when all service outlets are being used

Front 11

Pressure vessel

Back 11

must have a guage, drain, safety relief valve, and connections for the piping system

Front 12

Delta P

Back 12

The pressure between cut in and cut out is generally referred to as differential pressure . Should be 15 psi

Front 13

Automatic moisture traps

Back 13

should be installed at the lowest part on the receiver

Front 14

Oil seperators

Back 14

generally installed on the piping between the compressor and the receiver

Front 15

Aftercoolers

Back 15

Bring the temperature of the compressed air down to ambient temperatures, which make the system more efficient. Should be same size as the suction pipe and be installed between the compressor and receiver and graded towards the receiver

Front 16

Intercoolers

Back 16

Used in conjunction with 2 stage compressors. Their purpose is to cool the compressor air by 10 degrees Fahrenheit between the cylinder stages

Front 17

Air dryers

Back 17

Are installed downstream of the receiver tank

Front 18

Service outlets

Back 18

Equipped with quick connect hose couplings

Front 19

Reciprocating compressors

Back 19

Also known as piston type compressors, are the most common type of compressor for small and medium installation
