Charger Direct Pressure

Charger Direct Pressure
The Charger Production Pressure Blast uses a large 1.0 cubic foot capacity ASME Coded pressure pot with access port to pneumatically push the abrasive to the part using the nozzle size and blasting pressure to determine the compressed air usage. Because the blast nozzle is the air orifice and abrasive occupies space inside the nozzle, the pressure machines require less cfm to create the same abrasive velocity during operation. Direct pressure machines, including this model, produce faster abrasive particle velocity, higher abrasive grain density on the part and greater abrasive frictional heat. Additionally they will operate with the heaviest of blast media, steel shot and steel grit.

The Charger Direct Pressure Machine is designed for Production operation; we consider production operation to be one (1) hour or more of daily machine operation using a production gun size consuming about 45 cfm of compressed air. The negative pressure dust collector on this machine uses the most advanced cartridge filtration and effortless pneumatic cleaning cycle assembly. This design ensures a longer duty cycle, cleaner work area and longer blower service life. The replaceable cartridge style filter includes more than 200 sq.ft. of dust storage filter surface, cleans using a semi-automatic vibrator and requires only minutes to rebuild when required.

The capacity to store dust with ease of service is what makes this machine the right choice for Production operation. In addition, a larger dual filter option is available for higher daily operation or larger abrasive gun size.

With any increase in compressed air volume more frictional heat is created. Doubling the normal air usage reduces the blast time to only 1/3 of normal making cleaning speed almost a geometric progression and not simply arithmetic. It's this decrease in time and additional production passing through the machine that requires a much larger dust collector size.

NOTE: Standard Features are included with every model. Available Options can be added at additional cost and may require custom machine work, which may increase machine delivery time.

Technical Information: CHARGER Production
Machine Type: Dry Direct Pressure
Compressed Air Usage: 31 cfm @ 60 psi 3/16" nozzle (larger nozzles are available)
Suggested Air Compressor: The standard nozzle size requires a 3-phase air compressor; however, many small piston type air compressors will operate a smaller nozzle size, ask for details. Air compressors vary greatly, check the cfm output on the compressor being used or visit Air Basics for more information on compressor selection.
Pro Tip: Never buy a compressor using the displacement cfm number, always use the second cfm volume number listed with 90-100 psi inside the tank, because tank pressure reduces performance.
Recommended Abrasive Size: 60 to 150 mesh
Most Used Abrasive Type: Glass Beads, Aluminum Oxide and Silicon Carbide, Steel Shot & Grit. Please be aware that direct pressure must operate at much lower pressures than siphon pressure, most abrasives will exceed maximum impact velocity at 40 to 50 psi when using direct pressure.
WARNING: Abrasive Restrictions and Warning
Paint Specification: Environmentally friendly, high-grade polyurethane high gloss paint. Standard colors include MBA beige and high gloss light gray. Custom color matching is available using customer supplied color sample, please call 866-204-7068 for pricing.
