Overview windjet air knife

You may not give much thought to your drying and blow-off operations if you aren’t experiencing problems. But, new technology makes it possible to dry parts more thoroughly and quickly, improve precision in blow-off and achieve dramatic reductions in compressed air use. In fact, you may be able to save tens of thousands or even hundreds of thousands of dollars annually by using less compressed air or eliminating it completely.

In addition windjet air knife to improving operating efficiency and lowering costs, adapting new technology can help reduce noise and improve worker safety. Many plants use open or drilled pipe for drying and blow-off. These systems are inexpensive to make but very expensive to operate, are noisy and can be dangerous. There are many alternatives to consider.

To ensure air stream integrity, WindJet air knives feature a unique leading edge design that directs the airflow out of the knife in a straight stream. This design uses the Coanda effect and air entrainment to economically produce a uniform and constant air stream. The Coanda effect induces the supplied air to attach itself to the surface of the air knife and helps maintain the integrity of the air stream further downstream.

This effect also creates a condition conducive to entraining ambient air to increase the total volume of air. The result of this leading edge design is a uniform, high volume, constant air stream along the entire length of the knife. The spotting and blotching problems associated with many air knives are eliminated. Another advantage of the leading edge design is that it provides a visual guide for positioning the air stream, pointing out the direction of the flow.

This allows easy positioning of the knife to ensure maximum target coverage. Extended edge design improves air entrainment and ensures the integrity of the air stream.

Unlike other blower types, regenerative blowers are rugged, reliable and require infrequent, minimal maintenance. These blowers use a dynamic operating principle that recycles a certain amount of air and provide performance comparable to many multi-stage or positive displacement blowers.

In a regenerative blower, windjet air knife the compression space consists of a hollow circular ring between the tips of the impeller blades and the walls of the housing. In operation, the rotating impeller draws air from the inlet port into the compression space and moves it radially outward to the curved housing by centrifugal force. The action is called “regenerative” because a certain amount of air slips past each impeller blade during rotation and returns to the base of a succeeding blade for re-acceleration.

Overview windjet air Nozzles

Air nozzles convert a low-pressure volume of compressed air into a targeted high-velocity concentrated air stream, flat fan or curtain of high-impact air. Ideal for use in many applications, WindJet air nozzles come in a variety of types, capacities, sizes and materials. WindJet nozzles are widely used for moving materials and cleaning, drying and cooling parts. The high impact provided by these nozzles ensures effective drying and blow-off even for round or oddly shaped products.

A significant reduction in compressed air consumption compared to open pipes. Up to 60% reduction in perceived noise level, depending on the initial air pressure. At 100 psig (7 bar), for example, an open pipe would produce a noise level of 98 dBa while an air nozzle would produce 85 dBa, a reduction of 13 dBa and a perceived noise reduction of 60%

Improved safety. The design of WindJet air nozzles prevents dead-ending should the nozzle accidentally be placed against a flat surface . The targeted air stream delivered by the nozzles can improve the effectiveness and efficiency of drying and blow-off. More complete drying, even in cracks and crevices is commonly achieved

When space is limited and the process cannot tolerate any increase in temperature, WindJet low flow compressed air knives are an excellent option. High velocity, uniform air flows across the entire length of the knife. Drying and blow-off are fast and efficient and minimal air is used. Compared to a 3” (8 cm) pipe with three drilled holes, a 3” (8 cm) WindJet low flow air knife will use approximately 92% less air.

Noise level is under 70 dBa in many applications – lower than many compressed air options. Designed for small areas, low flow air knives are typically mounted close to the target. Maximum knife length (or combined length of all knives) is limited to less than 2’ (61 cm). Applications that only require one or two air knives can experience significant operating cost reductions by using WindJet low flow models.

WindJet variable air amplifiers produce a constant, high velocity air stream for very targeted drying and blow-off applications. Efficiency is maximized because additional free air is pulled through the unit along with the compressed air. Variable air amplifiers typically provide coverage in the ¾ to 4” (19.1 to 101.6 mm) range at a distance of 6” (152.4 mm). Commonly used for spot drying, blow-off and exhaust operations, WindJet variable air amplifiers are ideally suited to robotic applications as well.
