Performance Data

Select an opening size to give a suitable volume of air to be handled.Project a line between selected dimensions. From the point of intersection with line P-P, project a line across to the air flow rate required.Throw ( 1 way & 2 way blow), Jet Velocity and Total Pressure levels can be determined at the relevant points of intersection. Throw ( 3 way & 4 way blow), can be read horizontally.

Example:

Air Flow Rate = 0.1m3/sec

At points of intersection:-

Jet Velocity
Pressure Drop
Opening Size
Throw (1 Way)
Throw (2 Way)

= 5m/sec
= 16 Pa
= 300x150mm
= 4.4m
= 2.9m

By Projecting Horizontally

Throw (3 Way)
Throw (4 Way)

= 2.4m
= 1.7m
