500-Liter Screw Compressor

As a professional manufacturer in China, Huitengda factory would like to provide you high quality 500-Liter Screw Compressor, which is a medium-sized high-cost-performance industrial air source equipment newly optimized for small and medium industrial scenarios. Different from small tank compressors with insufficient buffer capacity and large split compressors with complicated installation, this model is equipped with a built-in 500L large-capacity air storage tank, combined with screw compression host, air purification system and intelligent control system to form a complete fixed air supply unit.

Featuring large pressure buffer, stable fixed installation, low energy consumption and steady air output, it perfectly solves common problems of conventional small compressors such as frequent start-stop, easy pressure fluctuation and insufficient peak air volume. It is the most suitable fixed air supply solution for small and medium processing workshops that require stable air pressure, low operating cost and long-term fixed-point air supply.

Unique Advantages

The 500L super-large air tank is the core differentiation of this 500-Liter Screw Compressor, bringing exclusive performance improvement compared with 200L/300L small-tank compressors:

1.Powerful Pressure Buffer, Zero Peak Pressure Drop

The 500L large-capacity air storage tank stores sufficient compressed air, effectively balancing instantaneous peak air consumption. When multiple pneumatic tools or single high-air-consumption equipment starts instantly, the air pressure remains stable without sudden drop, ensuring consistent processing precision and product quality. It delivers stable and reliable fixed-point air supply for workshop production lines.

2.Reduce Frequent Start-Stop, Extend Machine Service Life

Small-tank compressors start and stop frequently to supplement air, causing severe motor loss. The 500L large tank stores enough air volume, effectively reducing compressor start-stop times, lowering equipment wear and failure rate, and greatly prolonging the overall service life of the fixed unit.

3.Better Air Drying & Purification Effect

Longer air retention time in the 500L tank helps natural precipitation of water vapor and oil mist in the air. Cooperating with the built-in filtration and drying system, it further reduces air dew point and improves air purity, protecting precision pneumatic equipment and processing parts for long-term fixed production.

4.Adapt to Intermittent & Variable Air Demand

Perfectly fit the working mode of small and medium factories with unstable air consumption. The large tank reserves sufficient air volume to cope with sudden air demand surges, avoiding production pause caused by insufficient air supply during fixed-line continuous operation.

Core Energy-Saving & Functional Advantages

Permanent Magnet VFD Energy-Saving System

Equipped with high-efficiency permanent magnet synchronous motor and variable frequency drive system, the 500-Liter Screw Compressor intelligently adjusts operating speed and air output according to real-time air consumption. It avoids no-load power waste of fixed-speed compressors, saving 30%-40% of annual electricity cost for workshops. Combined with the large tank’s air storage advantage, the energy-saving effect for long-term fixed air supply is more prominent.

Stable & High-Purity Air Output

Multi-stage precision filtration and air drying system cooperate with large-capacity tank to output low-dew-point, oil-free and dry compressed air. Effectively prevent laser lens fogging, painting bubble defects and pneumatic valve blockage, reducing equipment maintenance frequency for long-term fixed production lines.

Low Noise & Stable Fixed Operation

Optimized silent fan and damping structure design, operating noise ≤70dB(A). It creates a low-noise working environment for fixed workshop stations, meeting environmental protection and production workshop standard requirements.

Full Intelligent Safety Protection

Built-in intelligent LCD control panel, supporting real-time data monitoring, automatic start-stop and fault alarm. Multiple protection mechanisms of over-temperature, over-pressure, overload and phase loss ensure safe and stable long-term fixed-point operation.

Application

This 500-Liter Screw Compressor is specially tailored for small and medium-sized processing workshops and fixed independent production lines, filling the performance gap between small portable compressors and large industrial fixed compressors:

FAQ

Q1: What is the advantage of 500L large tank fixed compressor compared with ordinary small-tank fixed screw compressors?

A1: The 500L large-capacity air tank provides stronger pressure buffer and air storage capacity for fixed air supply. It effectively avoids instantaneous pressure drop, reduces frequent start-stop of the machine, lowers equipment loss, and delivers more stable air pressure and better air purification effect than small-tank fixed compressor models.

Q2: Is this 500L fixed screw compressor suitable for laser cutting workshops?

A2: Yes. It outputs stable dry oil-free air with constant pressure, perfectly meeting the fixed air supply standard of small and medium laser cutting equipment. It can effectively prevent lens pollution and cutting defects, and is more cost-effective than large industrial fixed compressors for small and medium fixed production workshops.

Q3: Does the VFD configuration really save electricity?

A3: Absolutely. The permanent magnet variable frequency system matches air output according to actual fixed air usage. Combined with the 500L large tank air storage advantage, it avoids long-term no-load operation and frequent start-stop power consumption, saving 30%-40% of electricity every year for workshop fixed production.

Q4: Is the fixed equipment easy to maintain in daily use?

A4: The standardized fixed unit design is adopted with reserved independent maintenance ports. Daily oil replacement, dust cleaning and inspection are simple and convenient, no need for professional technicians, reducing later maintenance cost of fixed air supply equipment.
