Air knives and air curtains made to spec

Latest News

Spray Nozzle Engineering supply a range of Silvent air knives and air curtains that can be constructed to meet specific user requirements.

Compressed air has many uses in industry; to clean, dry, sort or cool processes during manufacture. Using an open pipe to supply compressed air can result in excessive noise levels and compressed air wastage.

To combat this, Spray Nozzle Engineering supply a range of safety air nozzles which reduce compressed air noise and usage.

When manufacturing lightweight composite panels for vans, trucks and trailers, a French company used compressed air to blow away excess plastic and dust and cool the panels.

A steel pipe containing holes was mounted across the panel width in order to supply the compressed air for blow off. This set-up created excessive noise and uneven and insufficient coverage.

As the panels vary in width (from 2.40m to 2.90m), a unique solution was required; a system of air nozzles where the outer nozzles could be switched on and off, according to the panel width in production.

Silvent designed and built an air knife consisting of 28, in-line 920 air nozzles, where the two outer nozzles could be turned off via a ball valve.

When manufacturing lightweight composite panels for vans, trucks and trailers, a French company, used compressed air to blow away excess plastic and dust and cool the panels.Two of these unique air knives were installed (one each above and below the panel in production), resulting in a marked reduction in the noise level and an effective and efficient use of the compressed air to cool and clean the panels.

The Silvent 920 air nozzle is a flat nozzle that provides a wide but thin line of compressed air. Constructed of zinc, the 920 air nozzle is most often used in air knife applications and can reduce noise levels by up to 77% and compressed air usage by up to 55%.

Silvent has a range of stainless air knives for both food and industrial applications, as well as pre-made manifolds for ease of installation.

Spray Nozzle Engineering is the exclusive supplier of Silvent’s  safety air nozzles, safety air guns and safety silencers in Australia and New Zealand.
