About sandblasting equipment
Sandblasting equipment on the dust collectors shelf is sandblaster nozzles, hoses, spare parts and accessories for airborne-particle abrasion. A sandblaster does what dentistry calls airborne-particle abrasion: it alters the surface of a material with abrasive particles propelled by compressed air. A blast cabinet is an enclosure in which the operator stands outside and works the blasting nozzle through openings. OSHA requires a blast enclosure to be exhausted so that air flows inward at every opening while blasting goes on.
A dust collector is a device, or a combination of devices, that separates dust from the air an exhaust system draws off. A sandblaster does what dentistry calls airborne-particle abrasion: it alters the surface of a material with abrasive particles propelled by compressed air.
The CDC reports that dental laboratory technicians can breathe in crystalline silica dust when mixing powders, removing castings from moulds, grinding and polishing castings and porcelain, and blasting with silica sand. Silicosis, the lung disease caused by breathing in that dust, is preventable.
How dust collection and sandblasting equipment differ
- Dust Collection & Filtration — Takes the dust out of the air that grinding, polishing and blasting put it into.
- Sandblasting Equipment — Works on the surface itself, with abrasive driven by compressed air.
- General Repair & Replacement Parts — Replacement motors, windows, shields, switches and media jars for the units.
- Hoses Tubing & Fittings — Hoses, hose ends, nozzles and disconnect kits: what joins a unit to the bench.
- Filters — Replacement filters, bags, screens and cartridge kits.
What to look at when choosing
Dust: blasting shatters the abrasive and the surface being blasted, and the dust formed contains particles small enough to be breathed in.
Exposure limit: OSHA limits respirable crystalline silica in the air to 50 micrograms per cubic metre, averaged over an 8-hour day.
Particle size and pressure: smaller particles at lower pressure remove less material with more precision, and larger particles at higher pressure remove material faster.
Noise: a study of dental laboratories names sandblasters among the equipment with high sound levels and puts compressed-air blasting at up to 105 dB.
