Do I need a certified Vacuum?

Certified vacuums are for the collection and control of combustible dust and flammable substances.

The housekeeping of these materials is taken very seriously and is regulated by the US Department of Labor. It is important to know if your workspace or business is at risk. Industries affected by combustible dust include Powder, Agriculture, Food, Pharmaceutical, Pesticide, Rubber Plastic, Textiles, Chemical, Recycling, Coal-fired Power, Wood and more.

The Occupational Safety and Health Administration (OSHA) defines combustible dust as "fine particles that present an explosion hazard when suspended in air in certain conditions."

Combustible dust is everywhere and requires special collection and control.

Combustible dust violations can easily add up to hundreds of thousands of dollars. Avoid costly repairs by knowing the risks and using the proper, certified cleaning tools. Eliminating hidden areas of dust on counter space, equipment and overhead pipes or shelves is critical.

In these situations, blowers are an ineffective means of cleanup as they blow dust from one area of your workshop to another. Certified, grounded, vacuum cleaners that can effectively absorb and contain loose dust and particles are ideal for combustible housekeeping. Units that comply with National Fire Protection Agency regulations are a great start for your certified vacuum search.

Unfortunately, more than 450 accidents involving combustible dust have killed nearly 130 workers and injured another 800+ since 1980, according to a Center for Public Integrity analysis by OSHA and the US Chemical Safety Board. These fires and explosions have caused deaths, wounds and the demolition of whole buildings. These incidents were caused by a variety of sources including sugar, nylon, fiber, coal, iron, plastic, dust and wood.

There are three elements needed for a dust fire to occur: combustible dust, oxygen and a heat source. What makes these incidents especially dangerous is the dispersion of this combustible dust throughout the air in a confined space. Dust and debris are inevitable in the manufacturing process, so it is important to learn as much as possible and take solid preventative measures to be prepared should an incident take place.

There are many preventative measures that can be used to avoid costly damages. A certified vacuum goes a long way to reducing work hazards, providing employee safety and increasing facility productivity within the entire work environment.

Why is Hafcovac so affordable compared to their competitors?

HafcoVac is family owned and we manufacture and test all our vacuums at our facility. We keep our prices lower by selling direct, and we pass the savings on to our customers. All of our parts and accessories can be ordered directly as well.

Is the Hafcovac certified and safe for Osha's Hazardous Environments and the NFPA?

Yes of course! We have been selling into OSHA Recognized Hazardous environments every day and are Certified to sell into Class I and II with our ATEX Certification. Plus, to ensure the safety of the unit, we had our HafcoVac sent to an OSHA Recognized safety lab, and they deemed it SAFE FOR USE in Class I, II and III ALL DIVISIONS. Our ATEX Certified Vacuums are the best fit and the most affordable on the market!

What kind of warranty comes with the Hafcovac?

All HafcoVac models come with an industry leading Lifetime Warranty. Because there is no motor that will burn out, you will only need to replace the consumable items (Filter, Filter Bags, Foam Silencer and Gaskets).

Why are compressed air vacuums safer than electric ones?

Because the HafcoVac uses compressed air to generate suction, there are no moving parts or any possibility of heat build up. This is what gives HafcoVac it’s Safety Standard and is preferred By OSHA and the NFPA for use in Hazardous Environments.

Why is housekeeping necessary to reduce combustible dust risks?

Combustible dust and other debris are byproducts of many industrial manufacturing processes. If unkempt, this dust can result in OSHA fines and health code violations. Worse, combustible dust can result in fires and explosions that cause severe damage and workplace injuries.

Can the Hafcovac be used for wet and dry applications?

Yes it can! Because there is no motor or moving parts to worry about, you can simply remove the Filter and use the liquid shutoff for wet clean up.

What is the S'HUSH Silencer and why is it so quiet?

Our S'HUSH Silencer reduces noise output to about 77dB eliminating the need for ear protection. The S’HUSH is available for all HafcoVac models and will also fit any HafcoVac vacuums you already own.

Drum Requirements

Steel drum must be a minimum of 18 gauge (1.2mm). There must also be exposed metal on top or bottom ring (grind to bare metal to ensure conductivity/grounding).
