Spider Arm Air Knife

✅ No blind spots: Multi-angle air blowing from both sides and bottom, covering bottle shoulder, bottle body and bottle bottom simultaneously to avoid counteracting airflow from opposite blowing.
✅ Closer to bottles: Smaller size than air knives, able to get close to bottle bodies past guardrails. Shorter air cutting distance leads to less energy loss.
✅ Fast bottle type change: Adjustable angle and height for air nozzles. No need to replace the whole system when switching specifications, quick and convenient adjustment.
✅ Thorough purging: Single bottle blowing duration is 3~5 times that of traditional air knife systems, with blowing cycles up to 10~20 times.
✅ Stepped layout: Air nozzles arranged from high to low following fluid mechanics. Water is pushed down step by step without backflow.
✅ Durable material: Main pipe is welded SUS304 stainless steel; air nozzles are made of POM (acetal). Long-term stable performance without deformation from -50℃ to 110℃.

Description

Typical Applications

1. Beverage and mineral water filling line: Blow dry the bottle body before applying labels.
2. Beer and beverage filling: Blow away residual water from the bottle walls and bottom to prevent label wrinkling.
3. Canned food, sauces, seasonings: Remove water from the bottle body and cap to prevent rust spots.
4. Cosmetics, cleaning and care products: After blowing dry the bottle body, apply labels and apply ink marks.
5. Pharmaceuticals, oral liquid bottles: Cleanly blow dry and reduce water stains and secondary pollution.
6. Bottled and boxed containers: Cut water from multiple angles instead of using a single air knife.

Key Features

1. Multi-angle wind cutting, no blind spots or dead zones.
2. The blowing time for a single bottle is 3-5 times that of the original.
3. Adapts to different bottle shapes, with convenient and quick adjustment.
4. Approach the bottle from the closest distance and maintain the wind cutting effect.
5. The number of single-bottle blowing times is 10-20 times that of the traditional wind knife system.
6. The wind nozzles in a stepped pattern cover the bottle body from top to bottom, in line with the principles of fluid mechanics.
7. Can be used in conjunction with Reitz high-speed centrifugal fans and Reitz high-pressure fans, with flexible and convenient application.

FAQ

Which one blows drier, the spider's tube or the wind blade?

The spider nozzles for bottle and can products have more advantages: When using two wind nozzles to blow simultaneously, they will cancel each other out, creating a blind area, and they cannot be approached due to the obstruction of the guardrail. The spider nozzle can be closely attached to the bottle body and perform multi-angle stepped air blowing. The blowing time for a single bottle is 3 to 5 times that of the air knife, and the remaining water stains are significantly less.

Can it fit different bottle shapes and sizes?

Yes. The flexible gooseneck nozzles are adjustable quickly and freely. We can customize the manifold and nozzle quantity according to your bottle shape, diameter and line layout.

Can it be compatible with the existing blower?

Sure, as long as the air volume and air pressure are matched. The spider pipe itself does not have power; it needs to be connected to a high-speed centrifugal blower or a high-pressure blower. When the number of air nozzles increases, the total air consumption rises, and when the original blower has insufficient capacity, the terminal air speed will decrease. It is recommended to calculate together with the blower.
