Air Knives

Airmasters Energy Saving Air Curtain also known as “Air Knives” provides an efficient laminar sheet of air for wide area cleaning and drying applications. Since Air Knives are a type of air amplifiers, they use a small amount of compressed air to deliver a powerful, high velocity, laminar sheet of air over wide areas such as moving webs, film, sheets, strips, auto bodies and other large assemblies and objects. Airmasters Air Knives are the perfect replacements for drilled or slotted lengths of pipe. In addition, the Air Knives offers up to 70% compressed air savings when compared to the drilled pipes.

Stainless Steel models are ideal for food, pharmaceutical, chemical and other applications where purity, high temperatures or corrosive environments are concerned.

Airmaster Air Knives increase thrust and velocity, reduced noise, excellent uniformity, and significantly outperforms any competing, wide blowoff device.

Use of Shims

Airmaster uses ONLY stainless steel shims in their Air Knife products as plastic shims wear out over time and require replacement, even with relatively clean air systems. Stainless steel shims are .002” (.050 mm). In most application this is adequate. However, velocity and force can be increased approximately 30% by adding a second .002” (.050 mm) shim. Shims may be stacked up to 5 sets. If using three or more sets however, the air inlets at the “ends” should be used to maintain even flow

along the Air Knife system. Otherwise a slight d op in pressure and flow will occur across from the rear inlet ports if they are usedwith three or more shims Note that noise levels and air use will go up with an increased number of shims.

FAQ


Can the Airmasters Air Knife be used with the Blower? +
No, Airmaster Air Knife is a compressed air type of Air Knife and not a blower type air knife. Blowers cannot be used for compressed air Air knives. The Source of air should be a compressor.
How much Pressure should be provided for Airmasters Air Knife? +
The minimum pressure required for the Airmasters Air Knife is 5.5 Kg/cm2 or 5.5 Bars.
What is the material of construction of the Airmasters Air knife? +
Airmasters Air Knife comes in three materials namely Aluminium, SS304 and SS316L. The shim inside the Air knife is of SS316L material.
Can I give the inlet connection to the Airmasters Air knife from the side of the Air Knife? +
The Airmasters Air knife has inlet connection option on both back and on the side.
Can I control the output flow coming from the Air knife? +
You can set the pressure according to your requirement. The flow of air is directly proportional to the output air from the air knife. If you provide less pressure the output air will have less velocity. If you increase the pressure of the air, then the velocity of the output air will increase.
How much pressure drop is expected from the Air Knife? +
A minimal pressure drop of 0.2 to 0.5 bars is seen in the Airmasters Air knife.
