Product Description

PVC air knife

Overview

The PVC Air Knife is an industrial device that uses a high-pressure blower to generate a high-velocity, uniform airflow through a narrow slot for drying, dust removal, and cooling applications.
Compared with metal air knives, PVC air knives are lighter, more cost-effective, and resistant to certain chemical corrosion, making them suitable for medium-to-low pressure environments that require lightweight construction and cost efficiency.

Advantages

1.Lightweight design for easy installation and reduced equipment load

2. More cost-effective than aluminum or stainless steel air knives

3. Resistant to certain acids, alkalis, and chemical corrosion

4. Uniform airflow for efficient drying and dust removal

5. Customizable length and slot dimensions

6.Low noise for comfortable operation

Applications

1.PCB Manufacturing: Water and dust removal after cleaning

2. Food & Beverage: Drying bottle caps, bottle bodies, and food surfaces

3.Printing & Coating: Drying ink and coating surfaces

4.Electronics & Precision Parts: Non-contact dust removal to avoid scratches

5. Conveyor Cleaning: Removing debris and dust from belts
