What size Dust Extractor do I need?
For a rectangle, multiply the length by width, then multiply that number by 28 to find the flow of CFM at 4,000 feet per minute (fpm) airflow. Find the largest CFM number out of all your tools, and that’s what you’ll go on for the required rating for your dust collector.
Who makes Makita dust extractor?
Makita U.S.A., Inc.
January 15, 2020, La Mirada, CA – Makita U.S.A., Inc., manufacturer of high-quality professional power tools and accessories, has introduced the corded 11 Gallon Wet/Dry HEPA Filter Dust Extractor/Vacuum, AWS™ Capable, (VC4210L) with more power than the previous model, VC4710.
What dust class is silica?
M Class (Medium Risk) Dust For dust generated by working with concrete or materials containing Crystalline Silica, the CTM 36 HD Autoclean is recommended.
How do you calculate duct size for dust collection?
Minimum of 3 x diameter of straight pipe, for example 8″ diameter x 3 = 24″ straight pipe . If clean air return is utilized from the dust collector, the outlet diameter should be a minimum 2″ larger • than the inlet to minimize resistance, slow down the air flow, and decrease the noise level.
What size pipe should I use for dust collection?
6”
But if the generating saw dust amount is high, better to stick with a 6” PVC pipe for an effective dust collection process with maximum airflow. Make sure not to go below 4” pipe sizes, because they will significantly cut off the airflow and reduce the suction power of the dust collection system.
How do you get more suction from a dust collector?
Clean your filters often! When the lower bags in a two- or four-bag chip collector fill up, the unit’s filter area is effectively cut in half. This not only reduces suction significantly, but the higher air pressure inside the bag also forces fine dust particles through the fabric and into the shop air.
Can you vacuum silica?
The best way to contain and remove silica dust is at the source. Whether from cutting, grinding, crushing or drilling, capturing the dust before it’s released into the air greatly reduces the risk of silica dust exposure. However, not any vacuum can be used.
What’s Worse asbestos or silica?
The Asbestos Illness Team at Hugh James in Cardiff, Wales, have investigated crystalline silica exposure, and when asked whether the substance is as dangerous as asbestos, they answered no. Crystalline silica is harmful but will only impact certain individuals with very specific job roles and exposure levels.
How do I design and size my dust collection system?
Dust Collection System Design Calculations
- Draw a floor plan of your shop.
- Determine Duct Velocity (FPM)
- Determine the Diameter and CFM of each Branch.
- Determine the Diameter and CFM of Main Duct.
- Calculate System Resistance (SP – Static Pressure)
