Negative pressure exhaust fan / vacuum fan/poultry greenhouse fan
1. The outline border adopts advanced automatic process, more accuracy,high zinc coated material.
2. The aluminum metal alloy of the high strength hub, adopts aviation aluminum magnesium metal alloy, light weight, high strength, good tensile.
3. Shutter adopt special push-pull centrifugal device, ensure shutter totally open and close, windproof, rainproof and dust-proof.
4. Newly punch forming fan blade, reasonable angel and reach the max. air flow, mini. Noise.
5. Double bracing (E style) belt transporter, Europe industry motor standard.
6. Safety net easily tears down.
7. Strictly quality test process: noise test, vibration test .concentric performance test, fan blade turning speed test, input air teat and vehicle efficiency test.
8. Special motor hole wind shield, avoid losing wind to reach the best wind suck effect.
9. Shell:SMC glass steel, having anti ultraviolet ray, acid and alkali resistance and corrosion rust.
10. Louver air flow principle is applied in designing, does not require the use of electricity and shut down to prevent ingress of water.
11. Integrated molding excluding metal combination.
12. Direct drive type design, low noise and large air volume. The bell can be configure to another
