In compressed‑air projects, choosing the right air‑end means choosing stable performance.

Industrial Compressed Air Systems

Introduction to the Airend — The True Heart of Any Compressed‑Air System

In every screw compressor, there is one core component responsible for converting all the motor’s mechanical power into compressed air. This is the airend — the functional heart of the machine. Inside its hardened housing, two precisely engineered helical rotors rotate in perfect synchronization, reducing air volume and increasing pressure during every cycle.

Even a deviation of just a few microns from the rotor’s designed tolerance can reduce system efficiency by up to ten percent. This is why the airend is the most critical element in the design, maintenance, and overhaul of any screw compressor.

The quality of an airend determines:

• how quiet the compressor runs under high pressure,

• how efficiently it consumes energy,

• and how many thousands of hours the bearings and rotors can operate before requiring service.

At Iran Compressor Sadegh, the airend is not just another consumable part — it is a strategic component in our supply chain. Its authenticity, assembly precision, and thermal performance must be guaranteed under all operating conditions.

Hanbell — Taiwanese Engineering with Global Standards

The primary focus of this page is Hanbell, a brand whose airend quality has moved beyond Asia and is now used as OEM equipment in many European compressor manufacturers. Founded in the 1990s in Taiwan, Hanbell developed multiple high‑performance airend series, each optimized for specific industrial applications.

A key advantage of Hanbell airends lies in their asymmetric rotor design. The angle and depth of the rotor profiles are engineered to ensure smooth compression, low pulsation, and minimal energy loss. Multi‑channel cast‑iron housings provide excellent cooling performance and maintain structural stability even at pressures above 13 bar.

Hanbell also utilizes Micro Oil Injection technology, precisely controlling the flow rate of lubricant injected into rotor contact points to ensure full lubrication and uniform heat dissipation. Industrial Hanbell models feature SKF X‑Series bearings capable of operating for more than 40,000 hours without requiring an overhaul.

Well‑known Hanbell series include DS for general compressed‑air applications, RC for screw refrigeration systems, LG for low‑noise medical and food‑industry compressors, and SR for OEM models supplied to other brands. Across all series, the design philosophy remains the same: high durability, low operating temperature, and minimal internal leakage.

Today, Hanbell is widely regarded as the first choice for many industrial suppliers in Iran. It delivers international‑level quality while maintaining substantially lower maintenance costs than European models — making it ideal for projects where stable pressure and long service life are essential.

Four Other Leading Airend Brands

Alongside Hanbell, Iran Compressor Sadegh also supplies airends from four major global manufacturers, each with its own engineering focus and performance profile — covering the entire spectrum from German precision to Asian durability.

Rotorcomp (Germany) is recognized as a benchmark of precision engineering. Its EVO rotor sets are manufactured using sub‑temperature machining to achieve near‑zero dimensional tolerance. Quiet operation and exceptional compression efficiency make it a preferred choice for sensitive industrial applications.

Atlas Copco (Sweden), a global leader in compressed‑air technology, produces oil‑free airends with nano‑seal thermal coatings, ideal for environments requiring ultra‑clean air. It is widely regarded for superior energy efficiency and extended service life.

ELGi (India) focuses on cost‑effectiveness and solid performance. Its airends are designed for continuous production lines and built from heat‑resistant lightweight cast alloys. Low maintenance requirements and easy parts support make it a practical industrial option.

Fusheng (Taiwan) is known for durability and wide OEM compatibility. Heavy cast‑iron housings and dual‑path lubrication systems ensure long rotor life, making it a popular choice in mid‑range industrial compressors.

Final Summary

The airend is the component where all the motor power and compressor engineering ultimately come together. Choosing the right airend means choosing long service life, stable pressure, and high energy efficiency. Hanbell, with its Taiwan‑based engineering and global‑standard performance, stands at the intersection of precision and durability. Combined with Iran Compressor Sadegh’s ability to supply Rotorcomp, Atlas Copco, ELGi, and Fusheng airends, every industrial sector can access the right solution for its specific pressure and reliability demands.
