Type-E Hot Air Knife | 1.5–4mm Wide Gap Hot Air Drying | QXY Air Knife

Type-E Hot Air Knife | 1.5–4mm Wide Gap Hot Air Drying | QXY Air Knife

Wide adjustable edge gap: 1.5 – 4.0 mm — suitable for stronger hot-air drying, heavier water removal, and higher airflow volume on production lines.

50W × 115H mm aluminium alloy body — a compact but stable chamber for heated air distribution across customized working lengths.

End, side M6, and bottom inlet options make pipe routing easier for horizontal lines, vertical frames, overhead equipment, and compact drying stations.

Φ32 / Φ38 / Φ45 / Φ51 inlet sizes support different blower pipe sizes and allow the air knife to match existing production equipment.

Factory-customizable length 100 – 4000 mm with High-Temp Silicone Gasket Seal (≤250°C) and full OEM/ODM support — each unit can be built to the required line width and installation layout.

Product Structure & Working Principle

E-Air-Knife-Design-drawings.png 

The 50W × 115H mm aluminium alloy body provides a stable chamber for continuous hot-air or blower-air delivery on drying and blow-off lines.

Air can enter from both ends, from the side M6 inlet, or from the bottom inlet. This allows the same body style to fit different machine directions and pipe routes.

After entering the body, air first fills the internal plenum. The chamber helps balance pressure along the full custom length, especially on long units up to 4000 mm.

The internal airflow path guides air toward the outlet edge and converts chamber pressure into a thin, high-speed air sheet for surface drying and cleaning.

The 1.5 – 4.0 mm adjustable outlet edge supports higher air volume and stronger surface impact for parts with heavier moisture, water film, or process residue.

Both ends use High-Temp Silicone Gasket Seal (≤250°C) to reduce leakage and keep the air chamber sealed during continuous heated-process operation.

Application Scenarios

The Type-E Hot Air Knife is suitable for heated drying and strong surface blow-off where a wider outlet gap and higher airflow volume are required.

Surface Drying — removes water film from bottles, metal parts, plastic products, and washed components after rinsing or cleaning.

Wide-Format Production Lines — custom length 100 – 4000 mm supports conveyor widths, panel drying, and continuous material processing.

Metal Sheet & Strip Processing — wider edge gap helps clear water, coolant, cutting fluid, and surface residue from moving metal surfaces.

Heated Process Equipment — High-Temp Silicone Gasket Seal (≤250°C) supports use around thermal drying sections and heat-assisted production lines.

Food & Beverage Packaging Lines — suitable for bottle, can, and package surface drying before labeling, coding, or inspection.

Automotive Component Drying Stations — supports stronger airflow where parts have complex shapes, cavities, or heavier remaining moisture.

Factory Capability · Customization · Service

QXY processes the 50W × 115H mm aluminium alloy body, inlet interfaces, outlet edge, end plates, and mounting details with CNC machining for consistent assembly accuracy.

Custom length is available from 100 – 4000 mm, based on conveyor width, heated drying area, machine frame space, or customer drawing requirement.

Configuration can be adjusted for inlet position, pipe diameter, wide 1.5–4mm edge gap, mounting method, and surface finish according to the user's equipment layout.

OEM and ODM orders are supported. Customers can provide drawings, samples, installation dimensions, or written application requirements.

High-Temp Silicone Gasket Seal (≤250°C) is fitted as the standard end sealing solution for this hot air knife series.

Prior to delivery, each unit can be checked by pressure test, edge-gap calibration, dimensional inspection, and visual inspection to confirm it matches the order specification.
