Precharged Cylinders
As an Alternative to Pogo Pump System
The area where a shop sprays Adhesive onto the Metal prior to applying Duct Liner is the messiest area in every Duct fab shops due to the nature of the wide Spray pattern from a Pogo style pump system, the operator adjustments to the nozzle and the tendency to overapply. Shops build a spray booth to contain the mess as best they can. Maintenance is often expensive and time consuming.
The removal of the pump from the equation in favor of Precharged Cylinders would remedy some of that effort of maintenance, and allow for more control in keeping the area less of a mess. It not only removes the Pogo Pump, fluid hose and air hose but also the drum itself and usually the buildup of used drums (which are not easy to dispose). The Precharged set up is also easier to use, doesn’t require an air hose and sprays in a 4” vertical line which means less overspray and less mess. Add to all this the very minimal cost of start up (all required is a $190.00 USD Spray Gun and a $100.00 USD 12 ft hose).
40 lb Precharged Cylinder Covers Approximately 4,600 sq ft
Comparison of Precharged Cylinders and 55 Gallon Drums…how many rolls can you spray before running empty?
- * Based on 550 sq ft for every gallon (a 55-gallon drum with 54 gallons would cover 29,700 sq ft).
- * Based on 115 sq ft per lb of precharged adhesive (a 40 lb cylinder covers 4,600 sq ft; a 187 lb cylinder covers 21,505 sq ft; a 375 lb cylinder covers 43,125 sq ft).
- Sell price of 187 lb cylinder: approx. $1,000 USD.
- Sell price of 375 lb cylinder: approx. $1,700 USD.
- Sell price of 54-gallon drum: approx. $1,000 USD.
Maintenance Tip
Some shops keep the Spray Gun in Mineral Oil each night but this can be avoided by keeping the valve open. Keeping the knob that opens and closes the valve from the tank to the hose open will keep the glue in the hose and the air out. Closing the valve will cause the adhesive to harden in the hose and gun. The only time to close is when changing over to a new cylinder.
