Product Description

Pulse-Bac 3690D Dust Collector with Drum


What is HPLM? Put simply, it’s the highest power to weight ratio you will find in a vacuum today. With the highest CFM of all the series, they weigh in at just 208lbs. HPLM vacuums supply all the power you need in a portable package that saves time and trouble. Designed to capture dust generated by surface preparation equipment, large power tools and for job site large-scale cleanup operations, the HPLM vacuums are ideal for work involving dust from concrete, sand, drywall, wood and many other non-combustible materials. A great fit for surface preparation and manufacturing, all HPLM Series is compliant with OSHA’s Silica Dust Rule.

  • Airflow: 450-690 CFM

Features & Benefits

hplm drum vacuum collection options

55 Gallon Drum Vac

The HPLM “D” models offer all the performance of their bagger counterparts, but give you the large collection volume of a 55 gallon drum. The 3690D & 2450D can be used with any standard 55 gallon drum and when not sitting on the drum, the vacuum head will fit securely onto the four caster dolly for easy transport. Just remove the drum and place the vacuum head on the dolly and attach the special T-Handle. Now you can pull the unit on/off the job site with ease. No pre-separators or trailers to load up like other machines and only one man needed to do the job.

HPLM Power Options

Like the 1000 Series HPLM vacuums are essentially identical on the outside and are available in different power and collection options. This combination of power and versatility makes HPLM well suited for a variety of applications.

The 3690 is a step up from its little brother and features a tri-motor power plant that provides a whopping 690 CFM & 110″ of lift. This unit offers the highest level of performance and is a great fit for large walk behind grinders & polishers and other large surface preparation equipment. Like the 2450 the 3690 is great in a manufacturing environment where it can provide dust collection for a variety of applications.

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.


More Power. Less Weight.

HPLM vacuums provide a huge amount of power on a lightweight frame. Designed to be used with large concrete grinders and other surface preparation equipment or as a dedicated dust collector for manufacturing machinery,  they provide a platform that is up to 70% lighter than vacuums with similar power levels.

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.

easy empty bagger

Easy Empty System

The Revolution 360 Bagger option features our patented Easy Empty Valve System. When the valve is opened to release the collected material into the bag, our specially designed vent ports allow air to continue to flow into the vacuum. This airflow stops dust from escaping and allows the vacuum to continue to run without the bag being sucked up into the canister. Once the debris has been dumped, you can tie off the Longopac® bag, remove it and start a new bag, without ever shutting off the vacuum.

Remote Start

Everyone has wanted this feature when they’ve started their tool before the vacuum. The remote fob included with HPLM Series vacuums can start the vacuum with the push of a button from up to 180 feet away.

standing empty feature

Standing Empty

We’ve made our awesome Easy Empty System even better with the addition of the Standing Auto-Close feature. This allows the user to open the dump valve releasing the collected dust & debris from a comfortable standing position and then automatically closes the valve once the lever is released.

Longopac Bagging

Popular with contractors in many fields, the Longopac endless bagging system provides a quick, dust-free bagging solution that has never worked better now that it is paired with Pulse-Bac’s patented Easy Empty Valve system.

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.
