About dust collection and filtration
A dust collector is a device, or a combination of devices, that separates dust from the air an exhaust system draws off. OSHA describes an exhaust ventilation system as two or more of these parts: an enclosure or hood, duct work, dust collecting equipment, an exhauster and a discharge stack.
A sandblaster does what dentistry calls airborne-particle abrasion: it alters the surface of a material with abrasive particles propelled by compressed air. A dust collector is a device, or a combination of devices, that separates dust from the air an exhaust system draws off.
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 collectors, sandblasters and cleaners 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.
- Ultrasonic & Steam Cleaners — Cleans with a liquid bath or a jet of steam instead of an abrasive.
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.
