Instructions for use
Do not install Silvent products until you have read and understood the Silvent Group General Instructions for use.
The data are based on measurements performed under the following conditions:
Maximum pressure
For our nozzles and air knives, maximum recommended working pressure is 1.0 MPa (145 psi) unless stated otherwise. For our air blowing guns, maximum recommended working pressure is 0.7 MPa (100 psi) unless stated otherwise.
Thread standards
G-thread
Cylindrical thread according to ISO 228/1. Use sealing washer, adhesive or thread tape during assembly. Another classification for this thread is BSP (British Standard Pipe Thread).
NPT thread (National Pipe Thread)
American Standard in accordance with ANSI/ASME B 1.20.1. Thread deformation achieves a seal.
M-thread
Metric thread according to ISO 68/ISO 724. Use adhesive or thread tape during assembly.
Conditions for measurements of blowing performance
• Feed pressure is measured at air nozzle air inlet.
• The blowing force is measured on a flat surface of 310 x 290 mm (12.20” x 11.40”) and with a distance of 200 mm (7.87”) from the air nozzle outlet.
• The sound level is measured at a distance of one meter (3.28 ft) from the air nozzle outlet and with the microphone perpendicular to the direction of the air jet.
• The air consumption is measured by a flow meter located immediately before the air nozzle inlet.
All technical data presented in this catalog apply at a feed pressure of 500 kPa (72.5 psi) unless stated otherwise.
Noise reduction and energy savings
The specific figures for noise reduction and energy savings on the product pages are based on replacement of an open pipe with a diameter as indicated for each product in the technical data.
Air supply
An important factor for the air nozzle(s) to function optimally is that the air supply must be large enough. Otherwise the flow might be turbulent and/or the blowing force could be unevenly distributed. For applications that use many nozzles mounted on a line the air supply can be divided among multiple inlets. It is also important that fittings and nipples do not choke the air supply.
