Air Inlet

Air inlet

Air inlet main Components
Windows: Plastic contains the anti-ultraviolet raw material, making it longevity.
Protection net: Reasonable Reasonable structure, material is Polypropylene.
Nylon pulley: Designed by patent organization, it is of rolling friction when turning on or off, low resistance and easy opening and closing.
Return Spring: High-quality stainless steel spring, durable and rustless.
Pulley Accessories: Rigidity hard-drawn wire round steel, ensuring accurately openingRigidly connected will not be stretched, the surface is treated by galvanization in case of rust.
Operation of air inlet
Operators watch the pressure meter in the house, and operate winch hands, until it reaches to the setting data

1. The open-close of air inlet adopt Nylon pulley and rolling friction, the resistance is low, and inner is filled with 20mm Polystyrene to ensure the warm-keeping of the air inlet.
2. A group of air inlet could be opened at three angels which can realize ever ventilation.
To realize uniform ventilation, angle of inlet near the fan should be smaller than those far from it.
3. Plastic contains the anti-ultraviolet raw material, making it longevity.
4. The spring of air inlet is stainless steel material, which is durable, rustless and not out of shape, the technics is delicate and ensure to be seamless after closing the air inlet.

Ventilated Style
Air Inlet Installation Parameter

(1). The wall surface must be flat.
(2). Below the windows 15mm where must can fix expansion bolt
(3). To avoid rain flowing into the house, the inner war under air inlet should be higher than the external wall.
