1 trouble-free: strict, long ball shape structure of lubrication and ball bearings, long life, no maintenance, also do not need to replace parts, the high precision sealed bearings chan quality assurance system to provide absolute.
2 with strong: bending and groove shape leaves into the combination of structural design, is the most durable power of ventilation equipment.
3 full use fan anti-corrosion: stainless steel, resistant to acid and alkali resistance, corrosion resistance, use more of the material is the best material ventilation equipment.
4 let rain characteristics: in the design of the listed absolute rainproof, it has the turbine blades rotating blades, when using the centrifugal force, will indoor air exhaust, and the rain stop into the blade with blades, because of the rapid rotation to fill gaps, even though each leaf blade attached in the small drips down the blade, also can flow to the roof, therefore, no power against the best results. Rain,
5 operation device: American chan high precision, high heat sealed bearing system for bearing the best synthetic oils can permanent self lubrication, lubricant, without the need to maintain, even in less than 2 kilometers of wind breeze, also can self.
6 prevent noise: use wind and airflow driving principle is not used, motor power from cost, operation, so silent noise.
7. No power is dustproof: 24 hours of operation, dirt easily, also do not need cleaning.
8. Weight: light weight light, power fan is lighter, in planning workshop structure, can need not worry roof load heavy.
9 daylighting: there is space between leaf blade with light, which enter indoor, can increase the illuminance.
