• Airflow Switches
  The Rotron Model 2C Airflow Switch is actuated by air velocity rather than air pressure. It is designed for easy mounting on the outside of an air duct with a small light weight stainless steel vane protruding through a hole in the duct into the airstream. The switch can be used as interlock for on off purposes or as a marginal safety device where the electrical contacts are operated at a predetermined minimum flow air.
  The switch is designed for commercial applications but has been used satisfactorily on certain military projects. Its acceptability on military projects is left to the evaluation of the purchaser.
  Operates reliably in ambient temperatures of 35ºC to +85ºC.

• Centrifugal Blowers
  Rotron centrifugal blowers are compact, sturdy, and relatively light in weight. They are designed for high performance while providig a long, maintenance-free life. Most models are available for either clockwise or counter­clockwise rotation, and in either simplex or duplex types. Models are available with 50/60 or 400 Hz AC motors.
  Centrifugal blowers develop high pressure-to-volume performance at low rotational speeds for quiet cooling of tightly packaged electronic equipment under severe environmental conditions in airborne, ground based, and shipboard applications.
  Simplex blowers have 1 squirrel cage impeller wheel while Duplex blowers have 2 squirrel cage impeller wheels mounted on a common shaft - both are available for either clockwise or counterclockwise rotation. Duplex blowers simplify ductwork and allow greater volume performance in tight locations. As with all squirrel cage blowers, air enters axially and exits tangentially, making a 90 degree turn.

• Inverted Blowers
  Trimline inverted blowers are compact, sturdy, and relatively light in weight. Inverted blowers have the unique Rotron inverted drive motor located inside the squirrel cage wheel. This results in unusual compactness and excellent motor cooling. Models are available in in a variety of Brushless DC and AC (50/60 or 400Hz) voltages Trimlines are compact and quiet designs for cooling electronic enclosures under severe environmental conditions in airborne, ground based and shipboard applications. They are well suited for applications when it is desirable to have air exit tangentially from a thin blower package and high pressure to volume ratio performance is required.

• Centraxial Blowers
  Centrimil centraxial blowers have an impeller that, unlike the centrifugal blower, achieves a substantial portion of conversion of velocity energy to pressure energy within the impeller itself. It is operated with a scroll so air enters axially and exits tangentially, making a 90 degree turn. Models are available with 50/60 and 400 Hz AC or brushless DC motors.
  Centrimil centraxial wheel blowers develop high pressure and volume performance at low rotational speeds than vaneaxial fans for quieter cooling of tightly packaged electronic equipment under severe environmental conditions in airborne, ground based, and shipboard applications.

  Radial blade blowers produce a higher pressure-to-volume ratio at higher speeds than is obtainable from the centrifugal blower. it particularly suitable for cooling tightly packaged airborne electronic equipment and ventilating NBC protection system filters and particle separators.

• Multistage Blowers
  Multistage designs range in size from 8 to 14 inch diameters. They employ the principle of several radial blade wheels mounted on a single shaft to develop uniquely high pressure-to-volume ratios at low rotational speeds by cascading pressurized air from one wheel to the next. Unusually compact and light in comparison to conventional multistage turbines, these blowers operate quietly and efficiently and contain no sliding or reciprocating parts. Models are available with 50/60 or 400 Hz AC motors.

Design For Chemical Processing Applications:
ROTRON® ‘CP’ Regenerative Blowers
Offer Unprecented Corrosion Resistance

ROTRON® “CP” regenerative blowers offer extremely high resistance to corrosion and chemicals encountered in the most demanding chemical processing applications. Their proprietary surface finish combined with optimized performance technology deliver key advantages for vent header off-gassing, spot source, bio-gas and/or landfill gas, and scrubber applications, among others.

ROTRON “CP” blowers benefit from the unique Chem-Tough™ finishing process, which converts their aluminum casting to a highly advanced plastic/ceramic surface creating unprecedented resistance to corrosion and chemicals, abrasion resistance equivalent to steel, increased hardness, and permanent dry lubricity.

These oil-free and low-noise blowers employ regenerative air technology to develop ideal air pressures and vacuums without the higher energy and maintenance costs typically associated with larger multi-stage or positive air-displacement blowers and compressors.

They supply clean, oil-free air; incorporate few moving parts (minimizing wear, tear, maintenance, and downtime); feature sealed blower assemblies for minimum leakage; and incorporate chemical duty motors with 303 Series stainless steel shafts for added corrosion resistance.

ROTRON “CP” blowers can achieve flows up to 1000 SCFM; pressures up to 230 IWG; and vacuums up to 174 IWG, depending on blower style. Standard blowers can be customized and augmented with optional accessories to satisfy particular application requirements.
