AMETEK Rotron - Propeller Fans - 10 Inch Premairprop

		Rotron Propeller Fans

Propeller Fans have sheet metal blades, usually four or more in number, which are curved to provide an aerodynamic lift and are generally arranged without blade overlap (PREMAIRPROP™ blades overlap). These fans operate best at free delivery or at very low static pressures.
Propeller Fans are suitable for conditions which require movement of a large volume of air against low resistance to flow. These fans are recommended for flushing cooling air through small enclosures such as radio cabinets, instrument panels, and communications equipment shelters.
They come in a variety of voltages and frequencies and are available with lead wires only. Most units are available with an optional internal Fan Performance Sensor (FPS) or external Low Speed Warning Device (LSWD).

AMETEK Rotron - Propeller Fans - Premairprop

		Rotron JFG/JFV Propeller Fans

Premairprop (10’’ Propeller)

The Premairprop model 10” diameter propeller fans has been developed to deliver more airflow at a higher velocity than the other products in its class. Models are available with airflow in either axial direction and with 50/60 and 400 Hz AC motors. The fan is operable at ambient temperatures of -55C to 70C and will meet all of the necessary requirements of military specification MIL-B-23071. In addition, Rotron can supply Navy standard vibration mounts, 11M15, which can be connected to the device and meet the requirements of MIL-STD-740, enabling the device to reduce structure borne noise.

The Premairprop is recommended for ground, radar systems and shipboard applications, but like other Propeller fans they provide flushing cooling air through large enclosures such as radio cabinets, instrument panels, and communication equipment shelters.
