The BNP 164 is the mid-size of the three ZERO tumble barrels, taking part loads up to 200 lbs in a 2.0 cuft barrel. Tumble barrel systems suit automotive rebuilders and small parts manufacturers — anyone processing repeat batches of hard parts that would take all day to blast one at a time by hand.
How it works
Inside the barrel the parts ride on a cushioning layer of media while #5 ZERO automatic guns clean, etch or shot peen their surfaces. Because the load is carried on media rather than dropped against bare steel, parts come out finished instead of dinged. The barrel interior is built from replaceable rubber-covered metal panels, so the wear surface is a service item rather than a reason to replace the machine.
ZERO offers tumble barrel cabinets with suction blast systems only.
LPDC dust collector
This configuration ships with the low-profile dust collector, which trades the RPH's tall hopper for a shorter package that fits under a lower ceiling. Same 600 cfm of extraction — it just takes less headroom, which matters in older shops and basements where a full-height collector will not stand up.
Electrical package
Supplied with the variable-speed drive package: blower on/off, 60-minute auto-reset timer, blast gun on/off, sequence on/off, barrel jog switch, variable-speed barrel drive, NEMA-12 enclosure. Variable speed matters more than it sounds — barrel rotation speed is how you control the aggressiveness of the tumble for delicate parts.
Common applications
- Remove residual sand from metal castings
- Beautify steel, stainless steel, aluminum, brass and other metals with a uniform matte finish
- Remove burrs, parting lines, flashings and other defects from castings and injection-molded parts
- Shot peen springs, journals, bearings, valve stems and tools to enhance strength and reliability
- Clean mold release and material buildup from molds
