Overview & Technical Specifications
01
Permanent magnet variable frequency screw air compressors are designed to minimize life cycle cost (LCC). The IP55 IE5 permanent magnet motor + high-efficiency ChiWai screw air end achieve up to 35% energy saving compared to traditional load/unload compressors. Available in single-stage (7.5–75 kW) and two-stage (75–315 kW) for even higher efficiency (15% more flow per kW). The Taiwan Linwei controller offers 14 protections, multi-language HMI, and remote monitoring. All models meet GB19153-2009 Grade 1 or 2 energy efficiency standards.
Applicable industries: cement packaging, woven bag factories, plastic granulation, textiles, food packaging, general manufacturing.Parameter

Success Stories & Trust
05
A Saudi cement bag factory replaced three 132 kW fixed-speed compressors with two HSL-1752BY (132 kW each) two-stage PM VFD compressors. Result: 28% energy saving (~$45,000/year), constant pressure 0.75 MPa, and quieter operation. HAOSEN provided full installation supervision.
-- Cement Bag Plant in Saudi Arabia
An Indonesian recycling plant needed compressed air for their pelletizers and bag making machines. HAOSEN recommended HSL-502CY (37 kW). The VFD reduced unloaded running time by 70%, cutting electricity bill by 33%. Customer ordered a second unit after 6 months.
-- Plastic Recycling Plant in Indonesia
"HAOSEN helped us choose the right size compressor and even redesigned our air pipe layout. The energy saving is real – we got payback in 14 months. Their engineer stayed 10 days until our team was confident." — Plant Manager, Vietnam

Solving Your Pain Points
06
| Customer Pain Point | HAOSEN Solution |
| High electricity bill from air compressor (often 40% of factory power) | PM VFD + Grade 1 specific power – cuts energy cost by 15–35% compared to fixed-speed compressors. |
| Frequent start/stop & pressure fluctuation | VFD maintains constant pressure ±0.01 MPa, no pressure spikes, extends equipment life. |
| Dusty, hot environment causes shutdown | Over-sized cooler (30% margin) + IP55 motor – operates reliably at 45°C, dust-resistant. |
| Hard to find skilled maintenance staff | Smart controller auto alarms for filter/oil change; HAOSEN provides on-site training and remote support. |
| Long downtime for spare parts | HAOSEN parts warehouses in India/SE Asia – common spare parts delivered within 3 days. |
| Need high flow for two-shift operation but low at night | VFD automatically adjusts flow from 30% to 100% – no wasted energy during low demand. |
