Reducing Air Consumption Lowers Operating Costs

Many mills use pipes with drilled holes or slits for drying or blow-off. This approach is extremely inefficient and consumes high volumes of costly compressed air.

Should you use compressed air and air control nozzles or blower air and airknives?

Here are a few guidelines:

Use compressed air and air control nozzles if:

• Your application needs maximum impact
• The nozzles need to be more than 4" (10.2 cm) from the target surface

Use blower air and air knives if:

• Your application needs velocity instead of impact
• The air knives can be placed less than 4" (10.2 cm) from the target surface
• The oil in compressed air causes quality control problems

Two ways to reduce air consumption

1. Compressed air nozzles

Air control nozzles that sue compressed air convert low-pressure volumes of air into a targeted, high-velocity stream or flat fan air pattern and provide many benefits:

• Significant improvements in drying or blow-off by increasing impact on the target
• A significant decrease in air consumption compared to open holes or slits in pipes
• Reduced noise level

2. Air knife packages with blower air

Using an air knife in conjunction with blower air produces a uniform, high-volume, consistent air stream along the entire knife length. The result is high-quality, consistent drying or blow-off. Plus the operating costs associated with an air knife package are quite low - even lower than the cost of using air control nozzles with compressed air.

There are several types of blowers available. Regenerative blowers offer several performance advantages:

• Lower noise
• Lower maintenance
• Longer life
• Lower operating costs
• Operates at lower speeds and achieves lower flows
• Fully customized solutions
