Offer kinds of Air Grilles and Diffusers
Application
Consistently popular grille style
Available in two blow patterns
Extruded aluminum construction
Fixed core  for easy access to ducting or volume control damper or filterÂ
Normally used in commercial installations requiring an air change rate up to about 10 times per hour, JIANPIN louvre are especially suitable where people are working for long periods of time, and draughts need to be avoided.
Weather Proof Louver  have been a popular product for many years, and are often the standard air terminal in offices and shops. The geometric design is both aesthetically pleasing, especially when used in a square tile ceiling, and also enables a 50% free area to be created, retaining high performance when used for both supply and extract applications.
Description
Disc valve suitable for exhaust air applications for isothermal conditions. Capable of handling variable airflow rates at moderately low pressure drops and noise.
Construction
Exhaust Metal Valves constructed from steel with mounting ring, providing long term strength and rigidity. The airflow passages are smooth ensuring quiet and efficient airflow. The centre cone can be wound up or down to adjust the airflow required to specific conditions and applications.
Performance Data
Data is based on Isothermal conditions with a room height of 2.7m with the diffuser mounted flush in an unobstructed ceiling. Pressure drops and Noise levels are tabulated with the adjustable centre cone of the valve at both 20% open and at 100% open. Noise Ratings are based on a room absorption level of 10db.
