epa spray gun transfer efficiency

0000020304 00000 n 0000017616 00000 n I seem to remember that conventional spray guns had a transfer efficiency of 40%, airless and air-assisted airless had transfer efficiencies of 40%, electrostatic spray guns where rated at 65%, and the dip operations above 90%. 0000003869 00000 n The shop is spending approximately $45,000 per year on coating purchases. and I would assume that based on current regulations the EPA would give them 0000005217 00000 n �E��ֿqm��Q��0ߋ V��R(��Ě[�K��n�;��K(ׇ�pjQ��cM[B�e(��F�T ��^��L�K��ǣu��͖�Ċ\,_cM��4�4q��Z�v=��6-�Dk$�� 3. for a total expense of $49,000 per year. then I suggest that you try to get hold of the CTG documents that were published transfer efficiency and minimize coating usage and overspray, including maintaining the correct spray gun distance and angle to the part, using proper banding and overlap, and reducing lead and lag spraying at the beginning and end of each stroke. 0000004062 00000 n depending on the size of the object being painted, the distance between the 0000024319 00000 n 0000095147 00000 n H��n$5��)|� ��e�a32�� in 1977 and 1978, respectively. 0000016005 00000 n 0000126678 00000 n spray cars using conventional spray guns (at 40% transfer efficiency) 1. 0000012395 00000 n 0000020882 00000 n Routine spray booth and filter maintenance, including filter selection and installation. ��tV( ��*¢M��FE�{0��e4�WJK��r�V�|�|�M�_Oj+X��j�8�ھ�vN�xR;9�b��k�P++KdL�Er�TY�Z9��-ʹn�Q��*��R��k��(��L��b��QKW 0000042512 00000 n In basic terms, transfer efficiency simply has to do with the amount of material that leaves the gun and how much of it lands on the surface you are coating (when applied properly). 0000023269 00000 n Please note that if an applicable federal regulation specifies a transfer efficiency, that efficiency must be used. If you intend to use the transfer efficiency table values in EPA calculations 0000096812 00000 n In this test, ten vertical six-inch wide panels are set up with 12 inch (304 mm) center spacing.The spray gun is held in a fixed position with no gun movement.
