Product Description

Introduction:
The ventilation window called the breathing window, ventilation window, according to the principle of air flow mechanics, adopt mechanical air exhaust, vacuum inlet design, do not open the window to achieve the indoor air discharging outdoor, outdoor fresh air purification after the balance of nature into the interior, the formation of indoor and outdoor air flow exchange, maintain indoor air quality.

Outline dimension:
1, long 600mm, wide 325mm, high 160mm.
2, long 645mm, wide 310mm, high 170mm.
3, long 690mm, wide 300mm, high 180mm.

Ventilation window:
1, this product is suitable for large-scale chicken farm, as a chicken coop in the ventilation equipment, effectively reduce the temperature inside the henhouse, ease the hen house, prevent the occurrence of various diseases;
2, can be directly installed in the chicken house wall reserved window;
3, the ventilation window is made of high quality engineering plastic mold, anti UV, anti aging, long service life;
4, protective nets: closed tight, reasonable structure, flexible, effectively prevent the birds into;
5, filled with 20mm polystyrene insulation board, effectively prevent the distribution of heat in winter;
6, pulley: the use of patented design, turn off for rolling friction, small resistance, easy switch;
7, reset spring: high quality stainless steel spring, durable without rust;
8, the operation of the window: by the operator to observe the negative pressure of the henhouse, manual operation winch, until the set value of the pressure gauge, or by the operator with experience control;
9, a group of air inlet window can open three angles at the same time, more reasonable ventilation;
The wind into the window 10, close to the fan open, away from the fan open, to achieve uniform ventilation with high quality and low price, suitable for the standardization of livestock and poultry house.


Vent window material:
Form: plastic with UV resistant materials, not aging, long service life;
PS (modified polystyrene) air door clamp;
Thermal insulation polystyrene foam protective net (polypropylene);
Plastic pulley: patented design, open and close for rolling friction, small resistance, easy switch;
Reset spring: thick stainless steel spring, durable and non rusting;
Block attachment: the rigid cold wire drawing, ensure accurate opening.
The connection is rigid connection and the error is small.


Characteristics of chicken coop ventilation window:
Each ventilation window can open three angles at the same time, more uniform ventilation.
Close to the fan inlet window opening small, away from the fan open up, to achieve uniform ventilation; air inlet windows open and close the plastic ferry, rolling friction, the resistance is small; the plastic form containing anti ultraviolet material, long service life; the air inlet window spring is made of stainless steel material, durable.

Ventilation window control device for henhouse:
Automatic control: by the environmental controller according to the set pressure difference control sheds, motor pull into the wind window door opening size, automatically reach the henhouse set pressure requirements.
Manual control: the operator to observe the negative pressure of the henhouse, manual winch, until the pressure gauge set value, or by the operator with experience control.
