Engineered for high thermal tolerance, low energy footprint, and 100% clean oil-free output for aquaculture, aeration, and light production.
Sri Lanka's manufacturing landscape is going through a massive transformation. Historically driven by tea processing and apparel, the island nation is rapidly upgrading its industrial infrastructure in hubs like Colombo, Gampaha, Hambantota, and Kandy. Modern wastewater treatment plants (operated under the National Water Supply and Drainage Board - NWSDB), food and beverage processing factories, pharmaceutical manufacturers, and chemical production lines are replacing older pneumatic and aeration systems with highly efficient alternatives.
In these industries, oil contamination is a fatal risk. Even a minor trace of oil carryover can destroy entire batches of food products, spoil pristine textile weaves, ruin chemical reactions, or harm biological cultures in water treatment aeration basins. Consequently, the demand for 100% dry, certified ISO Class 0 oil-free screw blowers is skyrocketing across Sri Lanka.
Many traditional factories in South Asia still operate old-generation tri-lobe Roots blowers. However, low-pressure screw blowers are fast becoming the gold standard due to their internal compression design. While Roots blowers compress air externally against backpressure (creating major energy loss and excessive noise), dry screw blowers compress the air inside the screw rotor chamber itself.
| Parameter / Feature | Traditional Roots Blower | Our Oil-Free Screw Blower | Impact on Sri Lanka Operation |
|---|---|---|---|
| Compression Technology | External (Backpressure design) | Internal Dry Screw Ratios | Saves up to 30-35% energy costs |
| Air Quality Level | Risk of oil leak through seals | 100% Oil-Free (Class 0) | Safeguards food & apparel quality |
| Acoustic Level (Noise) | Usually 90 - 110 dB(A) | Under 75 dB(A) with housing | Safer work environment in tight spaces |
| Speed Management | Fixed Speed (Mostly) | Variable Speed (VSD/PM Motor) | Matches varying aeration demands |
Sri Lanka presents unique environmental challenges for heavy machinery. With high relative humidity averaging over 80% and ambient temperatures reaching up to 40°C in industrial corridors, air compressors and blowers must be built to resist corrosion and thermal overload. Our screw blowers are engineered with specialized PTFE-based anti-corrosion rotor coatings, IP65-rated permanent magnet (PM) motors, and oversized air-cooled exchangers to guarantee seamless 24/7 operations even during peak heat periods.
Global procurement teams targeting South Asia look closely at total cost of ownership (TCO), grid compatibility, shipping lead times, and post-sales support. We address these critical checkpoints through:
Our dry screw air blower utilizes a twin-rotor profile designed with a high aspect ratio to optimize volume displacement. Controlled by a smart PLC inverter and a permanent magnet motor, the system continuously adjusts its RPM to match the real-time demands of the facility. This variable speed control eliminates hard-start energy spikes, reducing electrical strain on local industrial parks where grid stability can sometimes fluctuate.
Discover the core elements that make our oil-free screw blowers the smart choice for clean, energy-efficient operations.
Features integrated variable frequency drives and PM motors that reduce overall power usage by up to 35% compared to fixed-speed Roots blowers.
Designed with absolute physical isolation between the oil lubrication side and the compression chamber, ensuring completely oil-free air delivery.
Equipped with intelligent control units that monitor operational metrics in real-time, offering instant modbus communication for remote control rooms.
Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise founded in early 2004. Our advanced production and development center is situated at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China.

Q1: Can your oil-free screw blowers handle high ambient temperatures in Sri Lanka?
A: Absolutely. Our blowers are engineered with oversized cooling channels, highly effective heat exchangers, and high-temperature rated bearings. This allows them to run safely and continuously in ambient temperatures up to 45°C without automatic thermal shutdown.
Q2: How does the VSD Permanent Magnet (PM) motor help reduce utility costs?
A: Traditional fixed-speed blowers always run at 100% capacity and vent excess air when demand drops. Our Variable Speed Drive (VSD) system with a PM motor scales power consumption up or down to match real-time air requirements. This dynamic adjustment can cut energy use by 30% to 50% during off-peak times.
Q3: Are these blowers certified 100% oil-free?
A: Yes. Our dry screw blower elements use high-performance carbon ring seals and physical air gaps. This design keeps the compression chamber completely separated from the bearing oil sumps, ensuring zero risk of downstream hydrocarbon contamination.
Q4: What is the typical lead time and support structure for buyers in Sri Lanka?
A: Most standard configurations ship from Shanghai within 25 to 30 days. We provide complete online diagnostic support, installation guidelines, and keep a full inventory of replacement parts to support plants in Colombo and surrounding industrial zones.
