What Is the ATEX Intake Flange C-RA 10?

The ATEX Intake Flange C-RA 10 is an intermediate suction flange developed for installation on the inlet side of compatible C-Series ATEX centrifugal fans. It creates a defined circular connection point so that installers can attach ducting, adaptors, flexible connectors, or other approved ventilation components.

The intake side of a centrifugal fan draws air into the impeller. Therefore, the quality of the inlet connection directly affects airflow stability and fan performance. A correctly matched flange helps guide air into the fan while reducing gaps, misalignment, and unnecessary turbulence.

The C-RA 10 model is manufactured from copper and is intended for use with fan product reference 30301. Its published dimensional values include approximately 111.5 mm, 100 mm, 104 mm, 82 mm, and 83 mm across the identified A–E measurement points.

Although the focus keyword uses the phrase Explosion Proof Flange, the flange itself is a mechanical accessory. Its suitability for hazardous areas depends on its use with the correct ATEX fan, installation method, ducting arrangement, earthing provisions, and complete ventilation-system design.

Key Features of the Explosion Proof Flange

The Explosion Proof Flange in UAE provides a compact and secure inlet connection for compatible ATEX centrifugal fans. Its purpose-built construction helps simplify duct installation while supporting the integrity of the hazardous-area fan system.

• Copper Construction – The flange uses copper material, supporting compatibility with the non-sparking design approach of the associated ATEX ventilation system.
• Designed for Suction-Side Installation – It mounts directly on the inlet side of the centrifugal fan, where air enters the impeller.
• Fan-Specific Compatibility – The C-RA 10 ATEX model is intended for the compatible fan identified by product reference 30301.
• Compact Connection Design – Its small, defined dimensions help installers create a neat duct connection without an oversized transition piece.
• Improved Duct Alignment – The flange provides a stable circular interface, helping reduce misalignment between the fan inlet and ductwork.
• Industrial Ventilation Integration – Suitable for use with approved rigid ducting, flexible connectors, adaptors, and related extraction accessories.

How the ATEX Intake Flange Works

The ATEX Intake Flange acts as a mechanical transition point between the fan inlet and the connected duct system.

During fan operation, the centrifugal impeller creates negative pressure at the suction side. Air moves through the duct, passes through the intake flange, and enters the fan inlet. The impeller then accelerates the air and discharges it through the fan outlet.

The flange supports this process by creating a defined connection around the inlet opening. When installed correctly, it helps maintain a continuous airflow path and reduces unwanted openings around the duct connection.

A poorly connected inlet can allow ambient air to leak into the system. It can also produce turbulence, noise, vibration, and reduced extraction performance. Therefore, installers should match the duct diameter and flange dimensions carefully.

The flange does not generate airflow by itself. Instead, it supports the fan by creating a secure suction-side interface. Overall system performance still depends on the fan model, duct length, number of bends, filters, dampers, inlet conditions, and system resistance.

Selection, Installation and Maintenance

Correct flange selection depends on the exact fan model. The C-RA 10 ATEX is specifically intended for the compatible fan reference stated in the product information. Installers should not assume that similar-looking fan sizes use the same flange.

Before ordering, verify the fan reference, inlet dimensions, duct diameter, connection method, and hazardous-area requirements.

• Confirm that the fan matches reference 30301.
• Compare the flange dimensions with the fan inlet and duct design.
• Verify that the connected duct does not place excessive weight on the flange.
• Use suitable supports for long or heavy duct runs.
• Position the flange concentrically with the fan inlet.
• Avoid forcing an incorrectly sized duct over the connection.
• Use compatible sealing materials where required by the system design.
• Maintain electrical continuity and bonding where required by the hazardous-area risk assessment.
• Use conductive or anti-static ducting when specified.
• Prevent screws, fasteners, or loose materials from entering the fan.
• Keep the inlet clear of packaging, debris, tools, and foreign objects.
• Check that the connected duct does not obstruct the fan inlet.
• Avoid sharp bends immediately before the suction connection.
• Inspect the flange for dents, deformation, cracks, or corrosion.
• Check mounting hardware for looseness caused by vibration.
• Inspect flexible connectors for wear or air leakage.
• Clean deposits that could reduce the effective inlet area.
• Isolate the fan electrically before inspection or maintenance.
• Use qualified personnel for installation in classified areas.

The complete fan and duct arrangement should follow the applicable hazardous-area design, ventilation, mechanical safety, and electrical bonding requirements.

Certifications, Standards and Compliance

The flange forms part of a hazardous-area ventilation system. Therefore, compliance depends on the complete fan configuration and installation rather than the flange alone.

• ATEX Directive 2014/34/EU – Covers equipment and protective systems intended for use in potentially explosive atmospheres.
• IECEx Certification System – Provides an international conformity framework for equipment used in explosive environments.
• IEC 60079 Series – Covers equipment selection, installation, inspection, and maintenance in explosive atmospheres.
