Detailed Introduction of 37kW Permanent Magnet VFD Screw Air Compressor
Basic Specifications
Model: 50A / 0.8MPa Permanent Magnet Integrated Screw Air Compressor
Motor Power: 37kW
Discharge Pressure: 0.8MPa
Air Displacement: 6.6 m³/min

 

Five Core Advantages

Ultra-high energy efficiency, obvious power saving effect
Equipped with high-efficiency permanent magnet synchronous motor + VFD variable frequency control system. 
Compared with ordinary fixed-speed air compressors, it can save 20%-35% electricity under partial load working conditions. The motor maintains high efficiency at full speed range, effectively cutting your long-term production electricity cost.
Stable air output & reliable continuous operation
Direct coupling driving structure reduces power loss and mechanical failure points. The air displacement is steady at 6.6 m³/min, with outlet air oil content ≤3ppm, clean compressed air. It supports 24-hour uninterrupted operation for factories, mines, plastic, textile and food production lines.
Low noise & humanized air cooling design
Whole machine noise is only 59±2 dB(A), far quieter than traditional piston compressors. Adopts large-flow air cooling system, the outlet air temperature only rises 15℃ above ambient temperature, good heat dissipation avoids high-temperature shutdown and prolongs service life of internal parts.
Wide customizable range to match local market demands
Voltage & frequency can be customized to 3-phase 220V / 380V  60Hz specially for Brazil grid standard;
Cabinet outer shell color can be adjusted according to your brand requirements;
Complete parameter modification support for different air pressure needs.
Compact structure & easy installation & maintenance
Integrated all-in-one design, overall dimension 1210*960*1270 mm, total weight only 330 kg, takes little workshop space. Air outlet interface G1 1/2" matches standard pipeline fittings. Simple internal layout, daily filter and oil replacement can be finished quickly without complex professional tools.

This 37kW screw compressor is designed with a humanized structure focused on convenient daily maintenance, low service costs and long-term stable operation, fully suitable for long-hour industrial use in Brazil's factories, mines and processing plants.

 

1. Easy Access Design for All Consumable Parts
All core wearing components are arranged on the side door of the unit, with large removable maintenance panels. Operators can reach the air filter, oil filter, oil separator core and lubricant filling port directly without dismantling the whole machine or moving heavy equipment.
- Air filter: Quick snap-on structure, can be replaced in 3 minutes without tools
- Oil filter & separator core: Standard threaded interface, ordinary wrench is enough for disassembly
- Oil drain outlet is placed at the bottom front of the cabinet, convenient for regular oil change without oil splashing and ground pollution

 

2. Long Service Cycle of Consumables, Cut Your Regular Maintenance Expense
Matching high-quality multi-stage filter components and anti-oxidation special screw oil, the replacement cycle of wearing parts is longer than ordinary fixed-speed compressors:
- Air filter: 2000–3000 working hours
- Lubricant oil & oil filter: 4000 working hours
- Oil separator core: 6000 working hours
Less frequent replacement means fewer spare parts costs and less production downtime caused by maintenance. The outlet air oil content keeps ≤3ppm after long-term operation, avoiding secondary damage to rear drying and filtering equipment.

 

3. Intelligent Fault Reminder System to Avoid Unexpected Breakdown
The built-in VFD control panel monitors all running data in real time, including exhaust temperature, oil pressure, motor current and running hours. It will send clear English alarm prompts in advance for potential abnormal conditions:
- High temperature pre-alarm to remind cleaning cooling fan and radiator
- Blockage reminder for air filter and oil separator
- Timing maintenance reminder to record accumulated working hours
Early warning eliminates sudden shutdown during peak production, and reduces heavy overhaul cost caused by neglected small faults.

 

4. Efficient Air Cooling System Reduces Overhaul Frequency
Adopts large-flow axial cooling fan and wide-area radiator. The exhaust air temperature only rises 15℃ above ambient temperature, even in high-temperature Brazilian factory workshops. Low stable operating temperature slows down oil aging, prevents carbon deposit inside the main rotor, and greatly extends the service life of the main screw host - the most expensive core component of the compressor. Fewer carbon deposits mean no costly host disassembly and cleaning overhaul.

 

5. Simple Main Host Structure, Low Difficulty for Major Repair
The unit uses a direct-coupled drive design without transmission belts or gear boxes. There are almost no vulnerable transmission parts between the permanent magnet motor and screw rotor, removing frequent belt replacement, gear lubrication and alignment adjustment work.
When major inspection is needed, the integrated frame structure allows technicians to disassemble the host separately. We provide complete English maintenance manuals and spare parts catalogs for overseas agents, local maintenance workers can complete repair without professional training from the factory.

 

6. Standardized General Spare Parts, Stable Global Supply
All consumables and wearing parts adopt universal industry standard sizes, no exclusive customized special parts that are hard to source. We support factory direct supply of all maintenance spare parts at wholesale cost, and can ship spare parts together with your main unit order. For Brazilian customers, complete spare parts inventory support shortens waiting time for replacement parts, minimizing production stop loss.

 

7. Protective Structure Extends Machine Service Life
The whole cabinet adopts sealed dustproof design (IP23 motor protection grade). Dust, moisture and workshop debris are blocked outside internal components, effectively preventing circuit short circuit, motor wear and filter blockage caused by harsh factory environments. Regular simple surface cleaning can keep internal parts intact for many years, lowering the frequency of large maintenance cycles.
