304 Stainless Steel Non-Power Wind Driven Roof Ventilator
Natural Air Exhaust Fans
Non-Power Wind Driven Roof Ventilator Natural Air Exhaust Fans
Description
Non-power wind driven roof ventilator natural air exhaust fans use
304 stainless steel materail with a long life service, with
features of zero-cost operating costs, considerable energy
efficiency, economical installation costs, and low maintenance
costs, which are widely used in poultry chicken farms. Roof
ventilator working principle: Turbine ventilators use natural wind and air thermal convection
caused by the difference between indoor and outdoor temperature to
push the turbine to rotate so as to use centrifugal force and
negative pressure to expel the stale indoor hot air.

Roof Ventilator Natural Air Exhaust Fans Characteristics:
1. High-quality structure:
Rigid spherical structure, permanent lubrication of the upper and
lower ball bearings, to ensure a long life and maintenance-free, no
need to replace parts, Cases, the American PEER, UBC, Japan NSK
high-precision bearing system is fully enclosed and absolutely
excellent quality assurance.
2. Operation of precision equipment:
UBC high-precision bearing system is fully enclosed, high
heat-resistant synthetic grease lubricant, suitable for permanent
self-lubricating, non-lubricating best bearings. Be careful, even
if there is a breeze of less than 2 kilometers, it is
self-supporting.
3. Green ventilation:
Adopt the principle of natural wind drive, do not use motor power,
avoid the cost of non-electric operation, and do not stop the
self-turbine ventilator. Rotating, silent and no noise during
operation.
4. Wide applicability:
Light steel special-shaped slab roofs of various industrial plants
with unique angles in diameter can be installed with concrete
roofs. And does not need support, easy to install.
Maintenance Precautions
1. Under normal conditions, if the unpowered fan runs continuously for about one month, it is necessary to inject calcium-sodium-based grease or molybdenum disulfide grease into the bearing with a butter station. The fan runs continuously for 3-6 months, and the grease should be replaced once to fill 2/3 of the bearing space.
2. Regular maintenance of unpowered fans to eliminate dust and dirt inside the fans.
3. During the startup, shutdown or operation of the unpowered fan, if abnormal conditions are found, including temperature, vibration, noise, etc., they should be overhauled immediately.
4. Use the adjusting device to keep the triangle tape evenly tensioned and not too loose or too tight. The length of several triangle tapes should be the same as possible.
5. For unused standby machines or fans that have been out of service for a long time, the rotor should be rotated by 120°-180° regularly to prevent the main shaft from bending. Add a valve to the inlet or outlet of the roof unpowered fan, close it when starting, and open the valve after operation until it reaches the specified working condition, and the inner ring and the shaft fit tightly.
6. In order to ensure personal safety, the maintenance of the roof unpowered fan must be carried out during shutdown
