Description The 3690 produces 690 CFM with 110” of lift and weighs only 208lbs. That is 70% lighter than other industrial vacuums with similar performance. The 3690 supplies all the power you need in a lightweight, portable package without the headache of a pre-separator to drag around like other vacuums. No added equipment makes the HPLM series lighter on your pocket book and your back, not to mention easier to use and more productive on the job. The 2450 sits on the same frame as the 3690 and produces 450 CFM, with 110” of lift and weighs only 205lbs. Both units sit on a larger version of our popular Revolution 360 Bagger Cart that allows the user to dump debris while the vacuum is on and can move through any standard 36″ doorway. Now that is great job site mobility. The 2450 & 3690 feature Pulse-Bac’s Automatic Pulse-Clean Technology to keep the filters clean, so suction stays consistent. This complies with the new OSHA Silica Standard that requires vacuums have a “filter cleaning mechanism” when used with silica. Pulse-Bac is the only vacuum brand with OSHA & NIOSH recommended cleaning mechanism, a “back-pulse filter cleaning mechanism”. This fully automatic system features HEPA filtration that does not require the user to stop work to clean the filter, no disconnecting a hose and sealing the inlet with your hand, no compressor or other equipment to add weight and virtually no downtime. The HPLM Series of vacuums are design to collect large quantities of dust generated by manufacturing machinery and surface preparation equipment like: floor grinders, floor polishers, floor sanders, shot blast machines, concrete cut off saws and the like. These units comply with the new 2016 OSHA Silica Standard that requires vacuums have a “filter cleaning mechanism”. (OSHA Silica Standard) Designed to be easily moved and maneuvered, these Pulse-Bac vacuums do not require a pre-separator like other industrial vacuums. The HPLM series is ideally suited to be used as dedicated dust collector for a one process machine in a manufacturing or industrial setting and are excellent for sanding, grinding, abrasive blasting or capturing mineral dust, carbon black or toner dust, plastic and composite dusts; as well as talc and food additives to name but a few.
