Circulation Fans (HAF)
Horizontal Air Flow Fan Air Blowers
VALU-MASTER Horizontal Air Flow Fan
Acme's precise engineering has matched the proper propeller with a continuous duty motor to form a high air flow and low energy consumption fan. This fan offers the user maintenance free, long lasting equipment suited for use in horticulture and agriculture environments.
Check
These Features
- Propeller - Aluminum blades held securely in place by a steel spider and hub provide quiet operation.
- Motor - Heavy duty PSC, totally enclosed motor with automatic thermal overload protection and ball bearings is energy efficient. Motor can be used with variable speed control for more precise air movement.
- Guards - Two piece wire guard for easy access has a gray plastic coating to resist corrosion.
- Installation - Two piece rotational bracket provides a locking tilt adjustment for proper angle of air flow. "S" bracket provides two different dimensional mountings.
- Wiring - Motor comes factory wired on the "A4" with a six foot, three conductor cord with grounding type molded plug for easy installation. The "F4" motor has the specified cord shipped unattached.
HAF Fans available in 12", 18", 20", 24".
Available in 60 cycle (some sizes in 50 cycle on request).
3 phase available on large orders - made to order.

EDC 18 - EDC24 Air Blowers
Air blowers are developed to break up stratified heat, humidity and stagnant air. The unique propeller design is self-cleaning and, together with air flow rectifiers, allows the highest efficiency to be reached.
The
round housing and air flow rectifiers are made of a strong galvanised
sheet-steel. The 6-blade propeller is statically and dynamic balanced
for low noise and low vibration.
To improve aerodynamic efficiency, the air blower has been developed in Munters euroemme's R&D lab. The test chamber has been built according to ANSI/AMCA 210-85 Figure 15 specifications. Construction details and airtightness have been verified by personnel of the BESS Lab at the Agricultural Engineering Department, University of Illinois - USA.
- Air blower housing is made of strong, pre-coated, galvanised sheet-steel.
- Each motor is individually tested for 100"/#) quality control.
- Propeller is statically and dynamically balanced.
- Special hooks on housing permit the blower to be easily hung.
- The smooth air recirculation obtained by using air blowers helps to prevent condensation.
- Air recirculation helps to prevent crops disease and helps crops transpiration.
- Every blower is individually checked for quality.
