Frequently Asked Questions

We do not recommend modifying any DuroVac system for liquid use. These vacuums are purpose-built for dry applications, and unauthorized modifications can: create serious safety risks, void your equipment warranty, lead to vacuum system failure. If you have questions about your specific application, contact your DuroVac® representative or email sales@durovac.com before making any changes.

At DuroVac, we supply vacuum systems based on the specific application to give you exactly what you need to ensure the system provides enough power. DuroVac specifies each system based on the application details provided by the customer. This allows us to offer a vacuum that provides the right combination of suction, power and performance.

DuroVac supplies our famously tough vacuums to professionals world-wide.

We do not use wattage or amps when referring to vacuums. Industrial vacuums are rated based on horsepower (HP), and we have designed systems of up to 250 HP.

DuroVac believes in old-fashioned reliability, and we design long-lasting industrial vacuums to make your whole team happy. We supply our famously tough vacuums to professionals world-wide.

Yes, DuroVac vacuums are designed to collect many bi-products of manufacturing, including combustible dusts. Our systems are NFPA compliant.

Contact a DuroVac representative today and we can walk you through the process. You can also try the Vac Selector tool on our website.

Workers who inhale these very small crystalline silica particles are at increased risk of developing serious silica-related diseases, including silicosis, an incurable lung disease that can lead to disability and death. You can learn more about the dangers on the OSHA website.

HEPA filtration is required to remove silica dust from the air.

Filtration life is based on the individual application, but DuroVac is proud to be the only manufacturer who offers a warranty on filtration. We believe planned obsolescence is the enemy and our products are designed for years of heavy-duty use before replacement is required.

A HEPA filter is a high efficiency particulate air filter, designed to remove 99.97 percent of all particles that are 0.3 microns in size that pass through it. The HEPA standard is set by the U.S. government's Department of Energy, and it was developed for use in nuclear facilities in the 1940s.

Unlike shop vacs, which use high suction and a narrow hose, dust collectors have low suction and a wide hose. Dust collectors have at least two stages, where larger particles are separated from smaller ones. This helps keep the motor from being bogged down by larger particles, which usually translates to a longer lifespan. Dust collectors are stationary, where shop vacs are portable units that can be moved from location to location. Shop vacs are a little better at spot cleaning, but they aren’t equipped to handle large volumes or dense materials. Brooms and compressed air might temporarily clear one surface, but they only end up pushing dust elsewhere in the facility – this is why an industrial vacuum system, either central or portable, is needed.

No, filters cannot be washed and re-used. They must be replaced, but at DuroVac, planned obsolescence is the enemy and our products are designed for years of heavy-duty use before replacement is required.

When it comes to moving materials through a fixed network, central vacuum systems are at the top of their class. Central vacs cover long stretches of your facility, supporting multiple operators while maintaining strong performance. They’re also highly configurable, so you always get the solution you need.

Our modular systems are fully customizable, which allows us to create the exact vacuum system for the job at hand without forcing you to pay for features you don’t need or won’t use. Our industrial central vacuum systems start at about $15,000 USD.

Industrial vacuum cleaners are designed and manufactured to meet specific needs of users and particular tasks that are generally heavy to handle. The main differences between industrial vacuums and retail models are their efficiency and sturdiness. Industrial vacuum cleaners are characterized by their high performance, and they can work continuously for long periods.

At DuroVac, we pride ourselves on offering the lowest cost of ownership in the industry for our systems. In certain applications, a central vacuum system is the best option from a cost and functionality perspective. Our expertise in industrial central vacuum system design means we can deliver systems with maximum ROI. However, we also offer a wide variety of portable models to meet our customers’ needs.

The majority of central vacuum attachments are universal, with the exception of some custom attachments.

DuroVac offers both standard and custom attachments, depending on the purpose and environment you are cleaning. Use them to do more work for you with less elbow grease and effort on your part, improving efficiency and productivity. The vacuum attachments replace tasks that are typically manual (i.e. shovel and broom).

You can extend the length of your hose by using couplings to attach it to another section of hosing.

Yes. Smaller diameter vacuum hoses are often more maneuverable and flexible, not to mention lighter, and for certain applications there are performance benefits. Larger diameter hoses can pick up bigger debris with less likelihood of clogging.
