Transverse Spray Box and 
Recirculating System



All Stainless steel construction spray box for 
transverse anti-sap stain application

Description:

The system operates as follows: Product to be applied is metered into a batch tank system. The mixed fluid is then pumped to a day tank unit. The mixed fluid is then pumped to tips mounted on a top and bottom manifold within a negatively pressurized spray chamber where the mixed fluid is applied to all four sides of the lumber. Vapors created in the spray chamber are removed by our unique air knife suction system, which draws the vapor through a mist elimination baffle system, which turns the vapors into droplets for reuse.

end guns

All the excess fluid is then returned from the chamber and mist eliminator to the pump room where it is filtered through a rotary separator unit. Once filtered the clean liquid is returned back to the day tank for reuse.  Offset chainways ensure complete board coverage.  Automatic end guns ensure treatment of board ends for random lengths.
