Wall Type Registers with One-Way Adjustable Blades
Shahrokhi wall type registers with one way adjustable blades have multi parallel blades which can be fixed or moved around the auxial pins.
These registers used for supply , return or exhaust air.
Horizontal or vertical blades may be arranged for any deflect setting position
Calculation Table of Wall Type Registers with One-Way Adjustable Blades
The (figure) shows the air flow pattern for different blades setting. It is noted that the throw and drop will decrease as the angle of the deflection increased.
The blades will affect the spread as fallows:
- a) For 0 deg deflection (straight) angle, the total spread of the air stream is one-third of the throw.
- b) For 22.5 deg deflection angle, the total spread of the air stream is about 45 percent of the throw.
- c) For 45 deg deflection angle, the total spread of the air stream is two-third of the throw.
