The following hazards may occur during the normal use of the equipment. Please

read the following chart.

In order to operate the Compressor Unit safely and correctly, we have opted to use the following symbols to make you

aware of important points. These points relate to user safety and preventing equipment problems. Please pay close

attention to these sections.

Tampering with the Unit while under full or partial

pressure may cause an explosion.

Relieve all pressure from the Unit before attempting

any repair or maintenance work.

As the Unit starts and stops automatically , serious

injury may result from working on the Compressor with

the power still in the on position.

Shut off all power to the Unit before attempting to

repair or maintain the Compressor.

Safety Precautions

As the Unit starts and stops automatically, do not come

into contact with moving parts.

Shut off all power to the Unit before attempting to

repair or maintain the Compressor.

Air compressed by the Unit is not suitable for inhaling. It

may contain poisonous vapours harmful to your health.

Never directly inhale compressed air produced by

the Compressor.

Compressor Air End, Motor, and Tubing become hot

when running. Touching these areas may cause

severe burns.

Never touch the Air End, Motor, or Tubing during or

immediately after operation.

As the electrical compo-nents on the Compressor are

General Purpose and the Motor is Totally Enclosed

(TEFC), there is a potential for explosion, should

vapours be present in the area.

The Compressor must be a minimum of 20 Feet (6.1

Metres) from any source of potentially explosive

vapours.

Compressed Air System Design

In designing a compressed air system, there are several factors that must be considered. Though cost may

be a factor in most designs, it cannot be the final determining factor, especially where air quality, air volume,

and air pressure are critical.

Shown below is a typical layout of a compressed air system.

Air Compressor: is the heart of the compressed air system. Ensure it is sized for the

application, is installed in a safe and correct manner, and is

maintained according to the manufacturers guidelines.

Flex Hose: protects the building air lines from any undue vibration caused by

the Compressor, and allows for any mis-alignment between the

Unit outlet and the building piping.

Refrigerated Air Dryer: removes the moisture from the compressed air by lowering its

temperature.

Oil-Water Separator: separates the oil from the moisture drained by the Refrigerated Air

Dryer and Filters. The oil is trapped by internal Filters, while the

water is allowed to be dispensed to the building drain.

Separator Filter: acts as a pre-filter to the Refrigerated Air Dryer.

Coalescing Filter: removes oil from the compressed air

Vibration Isolators: absorb any vibration caused by the Compressor, allow for any

irregularities in the floor, and make the Unit marginally quieter.

Automatic Drain: drains the Compressor Tank on a regular basis.

Please refer to the drawing below, as it identifies the major components of a typical Air Compressor Unit

and their function. (Some Units may vary slightly from this design, eg. gas powered or base-mounted

Compressors.

Please refer to the Compressor Pump Service Bulletin provided with your Unit to identify the

part numbers, location, and quantities for your particular Compressor Pump model.

to enter the Tank, but prevents

the air from flowing back into

The Compressor Unit must be located in a dry,

clean, cool, and well ventilated area. If possible,

the Compressor should be located in a

separate room or area, away from the general

operations of the shop.

Allow room for easy access to the Unit for

maintenance purposes, as well as to ensure a

maximum cooling effect caused by the

Flywheel. To ensure that the Unit is cooling

properly, allow a minimum of 18” (0.5 m)

between the Beltguard and any adjacent wall,

etc. as shown below.

Ensure that the floor under the Unit is smooth

and level. The Compressor must sit squarely on

all four Feet.

Devair has available Installation Kits which

include a) (4) Isolator Pads for use under each

Foot, and b) stainless steel Flex Hose for

installation between the Unit Tank and the shop

piping.,

If anchoring a Unit to the floor, ensure that there

is roughly a 1/4” (0.75 cm) gap between the nut

and the Compressor Foot. Do not bolt down

tightly.

A Compressor Unit releases a great deal of heat

that, when not taken from the Unit area, could

cause severe problems. It is very important that

the Unit be located in a relatively large area or,

when in an enclosed area, cool air is introduced

and the heat is taken out, this by means of

intake and exhaust fans.

The amount of heat generated by an Air

Compressor is calculated by simply multiplying

the Unit Horsepower by 2500.

Example: 15 HP Unit x 2500 = 37500 BTU/hour

The Compressor must not be

operated in a confined area where

the heat from the Unit cannot readily

escape.

NOTE

Never clamp or bolt air receiver Feet

tightly to the floor or support

structure. Doing so may greatly

increase stress on the Tank, causing

it to weaken and/or fracture.

Compressor Oil for the Air Compressor, as it

has been specially formulated for your Unit, and

contains only two additives, a rust inhibitor and

an anti foaming agent.

The following Maintenance Kits are available

through your Devair Distributor, the Kits

including Devair Premium Oil and Air Filter (s).

Do not attempt to operate the Unit without

first checking whether there is Oil in the

Pump. Add Oil as required. Serious

damage may result from use, however

limited, without Oil.

Use of improper Oil may negatively a f fect

Compressor Pump performance or

shorten Pump life. Resulting problems are

not covered by the Devair Inc. Air
