Why Ruwac

For over 30 years, Ruwac Industrial Vacuums has been manufacturing explosion proof portable vacuum cleaners, and explosion proof central industrial vacuum systems ranging from 2 to 250 horse power. Our legally certified explosion proof vacuums are available for use in Class I and Class II atmospheres and are used around the world to collect and contain combustible dusts.

Specializing in safe collection of conductive metals such as Aluminum, Magnesium, Titanium and Zirconium, Ruwac’s Immersion Separation Wet Collectors have become the industry standard for the safe collection of conductive metals and high explosives.  Ruwac's industrial vacuums are known for their reliability, innovative design and superb filtration. Whether it be a housekeeping application or point of source extraction, let Ruwac be your solution for your industrial vacuum requirements.

Our industrial, explosion proof vacuums are available with single or three phase motors and compressed air powered venturis.  All of our vacuums are constructed out of only the finest materials and we ensure that every explosion proof vacuum system is fully grounded to eliminate any risk of static buildup.

Built in the USA, our explosion proof vacuums offer more filtration, increased vacuum, and custom hoses and accessories, all at the most competitive pricing.  No matter how many vacuums have failed you, we guarantee that our state-of-the-art filtration system will return only clean air to the workplace, creating a true dust-free environment!

Questions to Ask BEFORE Investing in a Vacuum

Ruwac has been designing and building industrial vacuums in the United States since 1985.  Each explosion proof vacuum is inspected before it leaves our dock so you are assured you get what you ordered and in top operational order.  We can custom design our equipment and accessories to meet your specific application.  Our prices are competitive but our service is extraordinary.

When shopping for an explosion proof vacuum consider these questions:

Check Mark Is it legally certified?  
(Ruwac vacuums are certified by ETL for use in Class 1, Division II, Group D, Class II, Division I, Group F & G for explosive situations).  More Information

Checkmark What warranty is available?  
(Ruwac guarantees the vacuum housing for life, the MicroClean filter for three years and the electrical components for one year).

Explosion Proof Electric Vacuum Features

Vacuum Features Breakdown

A:  Air Diffuser/Silencer

The exhausted air from the turbine is diffused to prevent the re-entrainment of laden dust.  The motor deck silencer provides a quiet working environment, even in continuous use.

B:  Vacuum Producer - Single or Three Phase

Multi-stage centrifugal turbine produces more suction using less horsepower than any other in its class.  Explosion proof TEFC Baldor® motor is maintenance free, rated for continuous duty and is completely serviceable at one of many locations nationwide.  All motors are UL and CSA listed through their manufacturer and are approved for use in Class II, Dust-Ex locations.

C:  Durable Housing

Constructed with 900 tons of pressure, compression cast composite housing will not dent, break or rust.  The carbon impregnated housing is chemically neutral and static dissipating (<10-6 Ohms) to eliminate static discharge.  Housing is modular to accommodate filter upgrades and is backed by our lifetime warranty.

Legal Certification of Ruwac Explosion Proof Vacuums

etl_lrg_logoLegally certified explosion proof vacuums have been tested and certified to meet standards of safety in explosive situations.  Ruwac explosion proof vacuums have been certified by ETL to UL and CSA standards and are safe for use in Class I, Div 1 and 2, Group D and Class II, Div 1 and 2, Group F & G.

There are no UL or CSA regulations that certify an air powered vacuum.  So, while not “certified,” Ruwac pneumatically powered vacuums are considered “intrinsically safe.”

A device termed intrinsically safe is “designed to not contain any components that produce sparks or which can hold enough energy to produce a spark of sufficient energy to cause an ignition.”  Ruwac pneumatic explosion proof vacuums meet the same standards as our electric vacuums but utilize a solid stainless steel venturi in place of the electric motor and switch.  There are no moving parts.  They are the safest air powered vacuums on the market.  These vacuums, thus, meet safety standards and are safe to use in Class I, Div 1 and 2, Group D and Class II, Div 1 and 2, Group F & G.

All About Immersion Technology

ImmersionSep

Metal dusts are explosive

Ruwac’s portable immersion separation systems are designed to safely collect explosive or glowing media. With 100% of the intake air being completely submerged in liquids the chance of an outside ignition source entering the vacuum, is safely ruled out. The importance of a machine that will insure not only the safety of the environment but also that of the employees is priceless. Contact us today with your specific application to see if an immersion separator may be your solution.

Some materials that may require an immersion separator include but are not limited to:  aluminum, magnesium, titanium, sodium azide, glowing embers, etc.
