Read and follow all instructions and Safety Precautions before using this

equipment

Description

The AGGS-522 is a production spray gun suitable for use with automatic and semi-automatic machines.
The design utilizes high volume low pressure atomization air (HVLP) to reduce overspray and improve coating
efficiency. To handle a wide range of coating materials the material passages are manufactured from high
grade stainless steel. Pressure feed material supply can be re-circulating or direct. A removable spray head
simplifies maintenance and cleaning of material wetted components. The gun is triggered by compressed air
to a single acting cylinder by a remotely positioned 3 way valve (supplied by user).

APPLICATIONS: General purpose solvent based and waterborne coating materials, food and pharmaceutical
processes.
IMPORTANT: These guns are not designed for use with highly corrosive or highly abrasive materials and if
used with such materials it must be expected that the need for thorough cleaning and/or the necessity for
replacement parts will be increased. If there is any doubt regarding the suitability of a specific material, advise
what material is to be used and/or submit a sample for test.

MODELS
The automatic spray gun type AGGS complies to ATEX regulations 94/9/EC, protection level II 2 G X T6
suitable for use in Zones 1 & 2.

For ordering information see chart for the selection of air cap, tip and needle combinations.

*NOTE: If you need to pre-set the flow rate, when using the AGGS-522 spray gun, by jetting material without
any atomizing air it will be necessary to compensate for the back pressure. The high performance of the
AGGS-522 is obtained differently to most other HVLP guns and so it will be necessary to increase the jetted
flow by approx. 30% to give the required atomised Low rate.

SAFETY WARNINGS

Fire and explosion

Solvents and coating materials can be highly flammable or combustible when sprayed.

ALWAYS refer to the coating material supplier’s instructions and COSHH sheets
before using this equipment.

Users must comply with all local and national codes of practice and insurance company
requirements governing ventilation, fire precautions, operation and house-keeping of
working areas.

This equipment, as supplied, is NOT suitable for use with Halogenated
Hydrocarbons.

Static electricity can be generated by fluid and/or air passing through hoses, by the
spraying process and by cleaning non- conductive parts with cloths. To prevent ignition
sources from static discharges, earth continuity must be maintained to the spray gun
and other metallic equipment used. It is essential to use conductive air and/or fluid
hoses.

Personal Protective Equipment

Toxic vapours – When sprayed, certain materials may be poisonous, create irritation or
be otherwise harmful to health. Always read all labels, safety data sheets and follow any
recommendations for the material before spraying. If in doubt, contact your material

supplier.

The use of respiratory protective equipment is recommended at all times. The type of
equipment must be compatible with the material being sprayed.

Always wear eye protection when spraying or cleaning the spray gun.

Gloves must be worn when spraying or cleaning the equipment.

Training – Personnel should be given adequate training in the safe use of spraying equipment.

Misuse

Never aim a spray gun at any part of the body.
Never exceed the max. recommended safe working pressure for the equipment.
The fitting of non-recommended or non-original spares may create hazards.
Before cleaning or maintenance, all pressure must be isolated and relieved from the equipment.
The product should be cleaned using a gun-washing machine. However, this equipment should

not be left inside gun-washing machines for prolonged periods of time.

Noise Levels

The A-weighted sound level of spray guns may exceed 85 dB (A) depending on the set­up being used. Details of actual noise levels are available on request. It is
recommended that ear protection is worn at all times when spraying.

Operating

Spray equipment using high pressures may be subject to recoil forces. Under certain
circumstances, such forces could result in repetitive strain injury to the operator.
