Air quality & quantity are both

necessary for textile quality

production- It pays to focus on

compressed air

• ISO 8573-1: 100% Oil-Free Air Allows Textile
Manufacturers To Maintain High-Quality Standards
• In addition to properly selected equipment, delivery quality
can be continuously monitored through instruments indicating
quantity of oil, dust and moisture in air.
