More Corrosion Resistant Than Competive Brands

Spark Resistant

ROTRON Regenerative Blowers
...Are made of aluminum, which is spark and corrosion resistant.

Competitive blowers are made of steel or other materials which are subject to corrosion.

Chem Tough

Chem Tough™
...A proprietary process -- combines the advantages of aluminum oxide ceramic and selected fluorocarbons to give ROTRON blowers unparalleled levels of chemical resistance, hardness, abrasion resistance, permanent lubricity and more.

 

Nuts Bolts

Oxidation
...Doesn’t stand a chance with the stainless steel nuts, bolts and other hardware that come standard on all ROTRON Chemical Processing Regenerative Blowers.

Competitive blowers use cheap zinc-plated fasteners that are prone to corrosion.

Spark Resistant

ROTRON Regenerative Blowers'
...Full C face motors are designed to protect motor windings and bearings from corrosive gases and the airstream.

Competitors often use half motors exposing these parts to corrosive gases, which can lead to blower downtime.

Explosion-Proof Motors Meet Stringent Safety Regulations

Safety iconSafest in the Market
 ROTRON explosion-proof motors are rated for Class 1, Division 1, Group D areas at a minimum, making the motors the safest in the market.

Most competitive blowers use Division 2 rated explosion-proof motors, which are not as safe as Division 1 motors.

 

Explosion proofMost Complete Variety
 Bison (formerly AMETEK DFS) strives to provide the most complete variety of explosion-proof motors, including Inverter-Duty motors that are ideal when using a VFD (Variable Frequency Drive) and Chemical-Duty XP motors that are perfect for handling corrosive and explosive gases.

 

Shield TemperatureThermal Protection
 All ROTRON explosion-proof motors have thermal protection, which shuts the motor off at specific temperatures via the customers’ control circuits.

Sealing Options Reduce Leakage for Optimal Gas Usage

Lo-Leak Lip SealLo-Leak™ Lip Seal
 Prevents leakage at the motor shaft. RTV sealing compound is used to cut off all leakage paths at the blower's metal-to-metal surfaces.

Double-Faced Carbon SealDouble-Faced Carbon Seal
 Prevents further gas leakage at the motor shaft via a pair of face seals working against each other on oppposite sides of a common mating ring.

Hermetically Sealed Mag Drive SealHermetically Sealed Mag Drive Seal
 Provides complete gas containment.
