Air Knives

Filter

Air knives are ideal for delivering high-pressure laminar flow of air by producing high compression ratio. They can be used to blow away debris, dust and other contaminants from surfaces, such as in machinery and conveyor systems.

Compact Air Knives, dBA, 1/4 Inch Inlet

Exair standard air knives are suitable for cooling, part drying or cooling off parts or items, as they move along the conveyor system. These air knives utilize the coanda effect to create air movement in their surroundings and deliver a uniform sheet of laminar airflow across the entire length with hard hitting force. They are engineered to significantly reduce compressed air usage and reduce the noise level up to 10 dBA, as compared to other "homemade" blowoff devices. These units are constructed of aluminium / stainless steel material for maximum corrosion resistance and are easy to install. Variants are available in air consumption rates ranging from 8.7 to 156 SCFM.

High Efficiency Air Knife Kits, 1/4 Inch FNPT Inlet

Exair air knife kits are used to enhance the working mechanism of air knives for cleaning, drying, cooling or blowoff applications. These kits include a super air knife, shim set, filter separator and a pressure regulator. The super air knives are used for delivering a quiet, hard hitting curtain of air across the entire length for maximum efficiency. Shim set allows increase / decrease in the force & volume of both consumed air & output airflow. Filter separators are ideal for separating water, dirt and scale from compressed air & keeping output clean while pressure regulators (w/ coupler) adjust the pressure required at the point of use and relieve undue pressures on fittings, hoses and tools. All models are CE compliant and are available in overall widths ranging between 3 and 54 inches.

Air Knives

Choose from a wide range of air knives, air wipes, static eliminating air knives and kits by Exair and Approved Vendors. Air knives are designed to produce a high-pressure laminar flow of air by producing an excellent compression ratio. They are ideal for use in cooling systems, blowing off liquid & debris from products and conveyor line applications. Exair's super air knives deliver a uniform streamline flow with 40:1 compression ratio & air inlet ranging from 8.7 to 156 SCFM, thereby producing a hard hitting blow. They feature aluminium or stainless steel bodies to handle the high compression ratios and 4 to 5 inlet ports for air intake. Depending upon at the material, they can handle airflow temperatures up to 800 deg F. Air wipes by Exair are an annular form of air knives and are designed to serve as an efficient blow-off system. These air wipes feature aluminium bodies with 1/4 inch NPT inlet ports and ring diameters ranging from 0.5 to 4 inches. These air wipes and knives are further offered in kits.

Frequently Asked Questions

How do I control the air pressure and flow rate of an air knife?

  • Air pressure and flow rate can be controlled using various methods, depending on the specific air knife and its application.
  • Some common methods include using a regulator, compressor and a filter for controlling the air pressure and using a restriction orifice or a valve to control the air flow.

How much pressure should be used on these air knives?

250 PSIG.
