Ametek Rotron Regenerative Blower
Model EN858BD72WL
This environmental EN blower is designed the same as the DR blowers, except added features include: heavy
duty cast aluminum manifold, spark resistant housing cover, impeller, muffler tower and manifold are vacuum
impregnated, Teflon® lip seal in a stainless steel case standard for leakage containment to 25 cc/min or less,
explosion-proof motors standard and available in a variety of world voltages, all metal-to-metal surfaces are
sealed with RTV sealant, and various UL explosion-proof listings. Consult factory. Environmental (EN)
regenerative blowers are also available in our Chemical Processing (CP) configuration: Chem-Tough(TM)
surface conversion corrosion resistant treatment for all castings, Teflon® lip seal in a stainless steel case
standard for leakage containment to 25 cc/min or less, stainless steel hardware throughout, and nickel plated
flanges and muffler retainers.

Rotron motors are designed to handle a broad range of world voltages and power supply variations. Our dual voltage 3 phase motors are
factory tested and certified to operate on both: 208-230 /415-460 VAC- 3 ph- 60 Hz and 190-208/380-415 VAC- 3 ph- 50 Hz. Our dual
voltage 1 phase motors are factory tested and certified to operate on both: 104-115 / 208-230 VAC-1 ph- 60 Hz and 100-110 /200-220
VAC-1 ph- 50 Hz. All voltages above can handle a ±10% voltage fluctuation. Special wound motors can be ordered for voltages outside our
certified range.
Maximum operating temperature: Motor winding temperature (winding rise plus ambient) should not exceed 140°C for Class F rated motors
or 120°C for Class B rated motors. Blower outlet air temperature should not exceed 140°C (air temperature rise plus inlet temperature).
Performance curve maximum pressure and suction points are based on a 40°C inlet and ambient temperature. Consult factory for inlet or
ambient temperatures above 40°C.
Maximum blower amps corresponds to the performance point at which the motor or blower temperature rise with a 40°C inlet and/or
ambient temperature reaches the maximum operating temperature.
Specifications subject to change without notice. Please consult your Local Field Sales Engineer for specification updates.

Voltage - ROTRON motors are designed to handle a broad range of world voltages and power supply variations. Our dual voltage 3 phase motors are factory tested and
certified to operate on both: 208-230/415-460 VAC-3 ph-60 Hz and 190-208/380-415 VAC-3 ph-50 Hz. Our dual voltage 1 phase motors are factory tested and
certified to operate on both: 104-115/208-230 VAC-1 ph-60 Hz and 100-110/200-220 VAC-1 ph-50 Hz. All voltages above can handle a ±10% voltage fluctuation.
Special wound motors can be ordered for voltages outside our certified range.
Operating Temperatures - Maximum operating temperature: Motor winding temperature (winding rise plus ambient) should not exceed 140°C for Class F rated
motors or 120°C for Class B rated motors. Blower outlet air temperature should not exceed 140°C (air temperature rise plus inlet temperature). Performance
curve maximum pressure and suction points are based on a 40°C inlet and ambient temperature. Consult factory for inlet or ambient temperatures above 40°C.
Maximum Blower Amps - Corresponds to the performance point at which the motor or blower temperature rise with a 40°C inlet and/or ambient
temperature reaches the maximum operating temperature.
