Push-pull Fan/Centrifugal Shutter System Exhaust Fan

详情

JL Push-pull Centrifugal Shutter Exhaust Fan 
1). Application: our push-pull centrifugal exhaust fan is widely used in poultry house, greenhouse, workshop and so on in the fields of Livestock Breeding, Agriculture, Flowers and Plants, Textile Industry, Mining, Chemical Industry, Pharmaceuticals Industry, Lumbering and so on. 

2). Material of JL Push-pull Centrifugal Exhaust Fan's components:
Frame: galvanized steel sheet, one-off molded, anti-corrosive, durable, zinc thickness: **0g/m2. Thichness: 1.0mm for the top, 0.8mm for the other sides
Blade: 6 pieces of mirror finished stainless steel blades, attractive and durable with big air volume. All the push-pull centrifugal exhaust fan's blades will pass the homeostasis test to ensure the air volume keeping the same as the very beginning during the operational life span, low noise, no distortion, no broken. Thickness: 1.2mm.
Motor: Siemens motor or Chinese motor, high efficient and energy-saving with CCC certificate. Protection class: IP *5. Insulation class:F grade. The voltage, HZ, phase and power can be customized.
Shutter: made of high strength galvanized steel sheet, dustproof and waterproof. Thickness: 0.*5mm
Centrifugal system/Push-pull System: made of high quality nylon, opening the shutters at complete *0 degree to ensure the lowest air resistance and biggest air volume. When the push-pull centrifugal exhaust fan is close, the tight sealing can efficiently block light and wind into the poultry house. The fasteners of centrifugal system/push-pull system are copper rivets, wear-resisting, no rust, and flexible.
Nylon oriented pole: made of stainless steel, ensuring the high strength and reducing frication, fixed on the flange which can avoid distortion of nylon and guarantee total concentricity of front and back bearing.
Protective net: made of hard-drawn wire, designed as door-type, which is convenient for maintaining.
Handles: designed as recessed type, easy for carry, transport and have no effect on installation and outlook.
Belt tensioner: made of high quality nylon or aluminium-magnesium alloy, avoiding belt loosening or dropping off, extending service life and avoiding distortion, waterproof
Belt pulley: made of aluminium-magnesium alloy by injection moulded, reducing the weight of blades and impeller, high corrosion resistance. Blast-sanding treatment for attractive appearance, eliminating internal stress to improve its own rigidity and stability, high strength.
Bearing: imported double-row bearing, super mute, high intension and durable, adopting special waterproof design, high intension, low noise, maintenance-free and long service life.
Belt: China famous brand belt, or Mistubishi belt.
