A Stout, High-End Contender.

‘Even when vacuuming fine concrete dust, there was never a noticeable loss of suction. I was able to use the vacuum for hours on end without needing to clean the filters. With the amount of suction the vacuum produced, it vented out an amazingly small amount of air with never a trace of dust.’

Features & Benefits

the mechanics of pulse-bac illustration/animation

Self-Cleaning Technology

Everyone has dealt with the trouble that a clogged vacuum filter creates, it takes up valuable time and creates a mess. Pulse-Bac solves this problem with our patented Automatic Pulse-Clean Technology™ that automatically cleans the filter while you work. Others may claim to have “automatic” or “pulse” filter cleaning, but look closely and you’ll see that they fall short of the original, requiring extra equipment like air compressors or manual gadgets that require work to stop for filter cleaning. These don’t truly solve the problem and make for more work. Only vacuums with the Pulse-Bac® name use our unique technology to automatically clean the filter while you work.

playHow it Works

Single or Dual-Stage HEPA Filtration

The 550H/1050H models provide Dual-Stage HEPA filtration. Dual-Stage filtration models, like all Pulse-Bac vacuums, feature the 5 Point HEPA Filter as an initial stage of filtration and an additional exhaust side HEPA filter. Both the 5 Point Filter and the exhaust side filter are individually tested to meet the 99.97% @ 0.3 microns standard required by most regulations and recommended when working with many materials. In fact, third-party testing of the 550H showed that our 2 stage filtration system actually provided 99.99% @ 0.3µm filtration, exceeding the standard.

Durable Steel Construction

Pulse-Bac® units are made for the rugged conditions of a job-site. We don’t cut cost with molded plastic tanks, cheap electrical components and off-shore manufacturing. With tanks made of 16ga. cold-rolled U.S. steel and a steel assembly covered with by a high impact ABS plastic hood, Pulse-Bac® is made to keep working even in the most punishing conditions. Even details like wheels are heavy duty, non-marking polyurethane casters, instead of molded plastic wheels on thin spindles. Add the fact that every Pulse-Bac is assembled by hand in our facility in Tulsa, Oklahoma and you’ve got quality you can’t beat.

Standard Auto Tool Start

Our Automatic Tool Start feature will start the vacuum for you when you start your tool. Plug your tool into the Automatic Tool Start and switch the power button to auto. When your tool activates, the vacuum will turn on automatically. When the tool turns off, the vacuum will run for 3 seconds to clear the hose before it shuts off.

1.5 inch locking inlet

1.5" Locking Hose & Inlet

Get a tight and secure fit each time you hook the hose up. The locking inlet locks in the high-quality crush proof hose so that it stays put while the unit is in use. This avoids accidental disconnects while working and ensures a good seal for maximum vacuum.

cyclonic debris management

Cyclonic Debris Management

The Cyclonic Debris Management system comes standard on all vacuum tanks, extenders, and preseparators. Our CDM system works with our pulsing technology and prevents upwards of 90% of dust and debris from ever reaching the filter. The CDM system stops dust and debris from constantly cycling up to the filters and holds it at the bottom of the tank until discarded.
