Huitengda factory's screw air compressors adopt permanent magnet VSD main engines to adjust rotating speed according to real air demand, achieving remarkable energy saving under variable load conditions. Ultra-precision ground rotors reduce internal air leakage. Featuring stable pressure, low vibration and low noise, they support long-hour continuous operation.
We offer various models including single-stage and two-stage types, oil-lubricated and water-lubricated oil-free versions, as well as integrated and split structures to satisfy different requirements on pressure, flow rate and air purity.

How to Choose the Right Screw Air Compressor?
When selecting a screw air compressor, evaluate on-site working conditions comprehensively.
-
Calculate workshop air demand and distinguish normal consumption from peak air use to confirm compressor displacement.
-
Define pressure and flow requirements for your process. Different production scenarios have different standards. Insufficient pressure or fluctuating flow will affect product quality.
-
Pay attention to compressed air quality, as oil and moisture can damage precision workpieces and pipelines. Ensure air dew point and purity meet standards.
-
Assess production mode. Heavy-duty models are preferred for round-the-clock continuous operation.
-
Check your existing dryers, filters and air tanks, and match parameters with the compressor to build a stable complete air source system.

FAQ
Q1: Why is energy consumption high?
A: It is usually caused by fluctuating air load, oversized units, rotor leakage or blocked heat exchangers. PM VSD screw compressors automatically adjust speed to save energy. Regular cleaning of heat exchangers also cuts power consumption.
Q2: What causes unstable discharge pressure?
A: Common reasons include pipe leakage, clogged air filters and worn rotors. Check pipelines and replace filters on time. Repair severely worn rotors for stable air pressure.
Q3: Why is there moisture in compressed air?
A: It comes from mismatched or faulty post-treatment equipment and high ambient humidity. Inspect dryers and filters, replace filter elements to keep the dew point qualified.
Q4: How to solve excessive noise and vibration?
A: It may be caused by loose foundation, aging bearings and damaged intake parts. Fasten the base and replace worn components to reduce noise and vibration.
Q5: What leads to high-temperature alarm and shutdown?
A: Dirty coolers, insufficient or degraded lubricant and poor ventilation. Clean cooling components, replace lubricant regularly and improve workshop ventilation.
Q6: Can you provide complete air source system solutions?
A: Yes. We offer one-stop supporting service for complete air source systems, including scheme design, installation, commissioning, training and reliable after-sales support.
