Both filter media can be purchased with a Teflon® coat, with ground continuity. Designed for applications where finely pulverized dusts have to be recovered. A dry recovery only model, the SS-35L EX can also be equipped with an interceptor, for the recovery of highly conductive metal dusts. Applications include: grain, flour and food processing, pharmaceuticals and dry chemical fabrication, plastics and more.

"Intrinsically safe" for non-electrical devices?

Claims to the effect that "pneumatically (air) operated (...) are intrinsically safe" make us raise an eyebrow...and yet, it is used by many manufacturers! For starters, an air-operated vacuum cleaner does not have electrical components. Everyone should agree on this. Intrinsic safety is a method of protection which allows electric equipment to be certified for use in hazardous locations. In North America, there is no existing certification process pertaining to non-electrical equipment destined for use in hazardous locations. Approvals for intrinsic safety cannot be obtained for non-electrical equipment, which are not regulated.

Real safety comes from choosing explosion-proof vacuum cleaners that are legally-certified and indicated for use in Class I, Group D and Class II, Groups E, F and G for hazardous locations. Legal certification by an accredited Nationally Recognized Testing Laboratory (NTRL) certifies only on the presence of the equipment in hazardous locations. A vacuum cleaner is therefore legally-certified for use in a specific location, not for the safe recovery of materials.

Only the manufacturer of explosion-proof vacuum cleaners can clearly state that his equipment can safely recover (or not) any hazardous/ toxic or designated substances. Tiger-Vac has developed guidelines and the Ex-Mat Recovery crest, stating that its explosion-proof vacuum systems are guaranteed capable of safely recovering combustible/ conductive dusts and/ or flammable liquids. No one else in the industry goes beyond the standard for consumer safety.
