In industrial environments where safety, efficiency, and compliance are critical, the demand for IE5 ATEX regenerative blowers is rapidly increasing. These advanced blowers meet the highest efficiency standards and comply with ATEX certification, ensuring safe operation in explosive atmospheres. While the majority of regenerative blowers on the market are available only up to IE4 efficiency level, the IE5 ATEX regenerative blower represents a breakthrough in performance and reliability. Dereike is also the only manufacturer currently available on the market that can produce IE5 ATEX fans.
An IE5 ATEX regenerative blower is a type of side channel blower that integrates IE5 ultra-premium efficiency motors with ATEX-certified components. These blowers are specifically engineered for hazardous areas where there is a risk of explosive gases, vapors, or dust. The combination of high efficiency and ATEX compliance ensures energy savings, operational safety, and regulatory compliance.
IE5 refers to the International Efficiency (IE) class for electric motors, with IE5 being the highest standard currently recognized. These motors are designed with permanent magnet technology or advanced synchronous reluctance designs, providing extremely low energy losses.
ATEX (ATmosphères EXplosibles) certification is mandatory for equipment used in potentially explosive atmospheres in Europe and other regulated regions. By choosing an IE5 ATEX regenerative blower, businesses benefit from:
Explosion-proof safety
Compliance with EU directives (2014/34/EU)
Reliability in critical operations
Reduced downtime due to strict quality and testing standards
IE5 motors can reduce energy losses by up to 20% compared to IE4. This translates into significant cost savings for facilities that operate blowers continuously, such as wastewater treatment plants, pneumatic conveying systems, and chemical processing facilities.
The ATEX certification guarantees that the blower will not become an ignition source even in Zone 1 or Zone 2 hazardous areas. This level of safety is essential in industries such as oil and gas, chemical manufacturing, and pharmaceuticals.
Because of their superior efficiency, IE5 motors generate less waste heat, which is crucial for maintaining stable operating temperatures in hazardous environments where overheating could pose a safety risk.
IE5 ATEX regenerative blowers are more compact and quieter compared to lower-efficiency models. The design improvements lead to easier installation in confined spaces and a safer, more comfortable working environment.
Below is a detailed performance comparison between different IE efficiency classes. This table highlights why IE5 is the gold standard for regenerative blowers.
| Efficiency Class | Typical Motor Type | Efficiency Level | Energy Savings vs IE2 | Heat Generation | Suitability for Hazardous Areas |
|---|---|---|---|---|---|
| IE2 | Standard Induction Motor | Standard Efficiency | Baseline | High | Not recommended for explosive atmospheres |
| IE3 | Premium Efficiency Motor | High Efficiency | 5–7% savings | Moderate | Limited (requires additional safety measures) |
| IE4 | Super Premium Efficiency Motor | Very High Efficiency | 10–12% savings | Low | Can be ATEX certified but limited availability |
| IE5 | Permanent Magnet / SynRM Motor | Ultra-Premium | 15–20% savings | Very Low | Ideal – Fully compatible with ATEX requirements |
This comparison makes it clear that IE5 motors deliver the best combination of energy efficiency, heat management, and safety.
Upgrading to IE5 ATEX regenerative blowers is no longer just an option — it is a strategic investment. With global regulations pushing toward higher energy efficiency standards, including the EU’s mandatory adoption of IE4 and beyond, businesses that adopt IE5 now gain a competitive advantage. The lower lifecycle cost, reduced maintenance requirements, and enhanced safety make IE5 blowers a future-proof choice.
Currently, the highest energy efficiency of non-explosion-proof side channel blowers (regenerative blowers) on the market is IE4. However, the explosion-proof blower from Dereike can achieve an energy efficiency of IE5. The IE5 ATEX regenerative blower stands out as the most advanced solution for industries requiring explosion-proof performance and maximum efficiency. By combining ultra-premium motor efficiency with strict ATEX compliance, these blowers deliver unmatched energy savings, reliability, and safety. As regulatory requirements tighten and energy costs continue to rise, investing in IE5 technology ensures your operations stay compliant, efficient, and competitive.
