Operational Description

The TEKNA spraygun is a lightweight professional gun designed to handle both water-based and solvent-based 

coating materials. Both HVLP and high efficiency models are available.
High volume, low pressure (HVLP) models are designed to reduce overspray and provide maximum transfer 

efficiency by limiting air cap pressure to 0.7 bar (10 psi) (complies with rules issued by SCAQMD and other air 

quality authorities).
HVLP models will produce approximately 0.7 bar (10 psi) air cap pressure at 1.8 bar (26 psi) gun inlet pressure 

with the trigger pulled. HVLP air cap #202 is designed for optimum basecoat applications. HVLP air cap #909 

is designed for optimum clear coat applications. Two air cap test kits are available (see 

Accessories

) which can 

be utilized to set the exact air cap pressure.
High efficiency models use air cap #7E7. These models are designed to provide optimum atomization of 

virtually all waterborne or solvent-based common coating materials at increased application rates while 

maintaining very high transfer efficiency. High efficiency models, when tested under recommended conditions 

with automotive refinishing materilas, have been found to exceed 65% transfer efficiency.
High efficiency models comply with SCAQMD rules and certain other air quality authorities. Refer to the website 

www.autorefinishdevilbiss.com

 for a complete listing of approved areas and requirements for regulatory 

compliance.

IMPORTANT:

 These guns are not designed for use with highly corrosive and/or abrasive materials and if 

used with such materials it must be expected that the need for cleaning and/or replacement of parts will be 

increased. If there is any doubt regarding the suitability of a specific material, contact your TEKNA Distributor or 

TEKNA direct.

NOTE: This gun is not to be used with halogenated hydrocarbon solvents or cleaning agents such as 
1,1,1,-Trichloroethane or methylene chloride. These solvents can react with the aluminium components 
used in this gun and cup. The reaction can become violent and lead to an equipment explosion.
