Screw fan

DLG seriesScrew fanContinuing the characteristics of low energy consumption, low noise, intelligence, and high stability of standard oil-free screw blowers, a specially developed small-scale blower is designed for small rural sewage treatment, aquaculture, oxygen supply and aeration sites that require low air volume and pressureScrew fanIt has the characteristics of small size, light weight, low noise, low energy consumption, and high degree of integration.

Product Features:

1. Small size: The main motor direct drive has low losses, high integration degree, and small footprint.

2. Lightweight: The host is made of cast aluminum material, which is lightweight and more advantageous.

3. High efficiency: Adopting permanent magnet variable frequency motor, the high-efficiency motor enhances the energy-saving effect. Compared to Roots blowers, the energy efficiency is more than 20% better.

4. Low noise: The operating noise is below 80 ± 5 decibels, providing low noise comfort.

5. High degree of automation: Automated control, simple operation, no need for dedicated personnel to guard, reducing labor costs.

6. Oil free: Front end contact seal, rear end double seal. Special sealing design to isolate lubricating oil from entering the compression chamber. The compression process does not involve lubricating oil, ensuring that the compressed air does not contain lubricating oil.

7. High stability: Variable frequency control, intelligent matching of speed, ensuring stable exhaust pressure.

Product Parameters:

Volumetric flow rate: 1.5~7.1m/min.

Exhaust pressure: 30-60kPa.

Motor power: 2.2~7.5kW.

Starting method: permanent magnet frequency conversion.

Application scope:

1. Village and town sewage treatment.

2. Pneumatic conveying.

3. Vacuum packaging.

4. Aeration for oxygen supply.

5. Aquaculture industry, etc.
