The difference between rainproof louvers and rainproof louver air vents

Rainproof louvers and rainproof louver vents have some similarities. They both have rainproof functions and are generally installed outdoors to achieve ventilation functions.

The difference between rainproof external louvers and rainproof louver air vents is the following points:

1:The rainproof louver air wall louver vent is generally installed at the air inlet of the air conditioning ventilation duct. When wall louver vent used as an isolated air inlet, the size is generally small. The blades are commonly used fixed and cannot be adjusted. The thickness of the frame is generally not more than 5 cm.

2:Rainproof external louvres are divided into single-layer fixed type, single-layer adjustable blade type, and double-layer fixed type plus adjustable blade type. The frame thickness is divided into 9 cm and 16 cm. Fresh air louvers can be installed separately on the exterior wall of the factory. Fresh air louver has good wind and rain resistance. The adjustable external louvres can be adjusted according to the ventilation volume. The size of the exterior wall can also be larger.
