Product Overview<\/strong><\/p>\n

The A-A Series Aluminum Air Knife is small and works very well. It is used for drying, cleaning, and air curtains. It is very thin at 50 mm by 125 mm. You can choose any length from 50 mm to 4000 mm. The A-A model fits in tight spots on the production line where space is low but you need even air. There are three air inlet options: the ends, the side, and the bottom. This makes it easy to install in different machines.<\/p>\n

Product Details<\/strong><\/p>\n

Product Name<\/strong>:\u00a0<\/strong>A-A Strong Air Knife \u2014 Small Aluminum Air Knife<\/p>\n

Primary Function:<\/strong>\u00a0<\/strong>It makes a fast, even air sheet for drying and cleaning in small spaces.<\/p>\n

Main Advantage:<\/strong>\u00a0<\/strong>The A-A body is small (50 x 125 mm). It fits in machines where big air knives cannot go. You can adjust the gap from 0.1 mm to 4.0 mm. The three air inlet options let you set the air without changing any hardware.<\/p>\n

Structural Composition:<\/strong>The A-A Air Knife is machined as a single aluminum alloy extrusion. Its internal geometry is purpose-designed to minimize flow resistance and maximize exit velocity consistency along the full knife length:<\/p>\n

\u2022\u00a0Three inlet configurations: end entry (both sides), side entry (M8 thread), or bottom entry<\/p>\n

\u2022\u00a0Silicone gasket seals at both ends for airtight pressure containment<\/p>\n

\u2022\u00a0Low-resistance plenum chamber for uniform static pressure distribution<\/p>\n

\u2022\u00a0Precision-machined tapered internal duct to accelerate airflow toward the exit slot<\/p>\n

\u2022\u00a0Adjustable narrow slot outlet \u2014 edge gap settable from 0.1 mm to 4.0 mm<\/p>\n

\u2022\u00a0Compatible inlet pipe diameters: \u03a638, \u03a645, \u03a651, \u03a660<\/p>\n

Technical Features<\/strong><\/p>\n

Wide Edge Gap Range (0.1\u20134.0 mm)<\/strong>: \u00a0<\/strong>A broader adjustment range than most standard models, enabling this knife to handle everything from ultra-fine mist removal to high-volume air curtain generation within the same unit.<\/p>\n

Three Inlet Position Options:<\/strong>\u00a0\u00a0<\/strong>End-entry (both ends simultaneously), side-entry, and bottom-entry variants are available. Dual end-entry allows balanced pressure feed from both sides on long knife installations, reducing velocity drop across the blade length.<\/p>\n

Compact Cross-Section (50W \u00d7 125H):<\/strong>\u00a0The air knife is very thin. It fits easily into old machines and small spaces. Use it where you do not have much room.<\/p>\n

Short to Long Length Flexibility:\u00a0<\/strong>We make these in many lengths. We have short ones at 50 mm for drying single parts. We have long ones up to 4000 mm for big sheets of glass, metal, or cloth.<\/p>\n

Silicone Gasket End Seals:\u00a0<\/strong>There are silicone gaskets on both ends. These gaskets handle high heat. They stop air from leaking out the sides. This keeps the air speed the same from one end to the other.<\/p>\n

Lightweight Aluminum Construction:\u00a0<\/strong>The aluminum body is very light. It is easy to move or change the angle during setup. Even though it is light, it is very strong. It handles high air pressure without any problems.<\/p>\n

Attention \/ Usage Notes<\/strong><\/p>\n

1.\u00a0Avoid Impact on the Knife Edge.\u00a0<\/strong>\u00a0<\/strong>The precision outlet slot is calibrated at the factory. Physical contact during handling, installation, or maintenance can distort the gap geometry. Always protect the knife edge during transport and positioning.<\/p>\n

2.\u00a0Keep the Air Supply Clean and Dry.<\/strong>\u00a0\u00a0<\/strong>Install an inline filter (40 micron or finer) upstream of the air inlet to exclude particulates. Use dry air where possible \u2014 moisture in the supply line can cause internal condensation and uneven airflow.<\/p>\n

3.\u00a0Match Inlet Size to Your Supply Line.\u00a0<\/strong>\u00a0<\/strong>Select the correct inlet diameter (\u03a638, \u03a645, \u03a651, or \u03a660) for your existing pipework. Mismatched connections reduce pressure efficiency and can cause turbulence at the inlet.<\/p>\n

4.\u00a0Set the Correct Installation Distance.\u00a0<\/strong>\u00a0<\/strong>For optimal drying performance, position the air knife 5\u201320 mm from the target surface. The slot centerline should face the work surface squarely. Angle adjustments of 15\u201330\u00b0 may improve water-blowoff efficiency on inclined substrates.<\/p>\n

5.\u00a0Do Not Modify the Factory Edge Setting.<\/strong>\u00a0\u00a0<\/strong>The outlet gap is factory-set to your specified width. If a different edge gap is required for a process change, contact our technical team for recalibration. Unauthorized adjustments may void the product warranty.<\/p>\n

6.\u00a0Schedule Regular Cleaning.<\/strong>\u00a0\u00a0<\/strong>Inspect and clean the inlet port and outlet slot during routine maintenance intervals. Accumulated dust, oil mist, or fiber residue narrows the effective outlet gap and reduces airflow velocity over time.<\/p>\n

Product Applications<\/strong><\/p>\n

The A-A Strong Aluminum Alloy Air Knife is actively deployed in PCB wash lines, LCD glass cleaning machines, ultrasonic component cleaners, bottle and label drying conveyors, metal strip drying systems, textile moisture control lines, and industrial air curtain installations across manufacturing facilities worldwide.<\/p>\n
