0700000393 - ESAB Eco Air Replacement Blower Unit

Technical Overview of the ESAB Eco Air Motor Unit

The ESAB Eco Air Motor (SKU: 0700000393) is the central blower assembly designed specifically for the ESAB Eco Air Powered Air Purifying Respirator (PAPR) system. As the core component of the respiratory protection unit, this motor is engineered to draw ambient air through P3 filters, delivering a consistent stream of clean, purified air to the welder's helmet. This replacement unit is critical for maintenance and repair operations where the original motor has exceeded its service life or suffered mechanical failure.

Technically, the unit features an intelligent flow control mechanism. It is calibrated to deliver a nominal airflow of 170 liters per minute, with boost capabilities up to 220 liters per minute depending on the setting and filter load. The motor housing integrates the necessary electronics to monitor airflow resistance and battery voltage. It provides feedback to the user via audible and visual alarms, signaling when the filter is clogged or when the battery charge is critically low. This ensures that the system maintains the required Assigned Protection Factor (APF) during operation.

Replacing the motor unit is a direct swap for the original component within the Eco Air assembly. It connects seamlessly with the existing battery packs, hose connections, and waist belts utilized in the Eco Air ecosystem. By utilizing this OEM part, facilities managers and safety officers ensure that the equipment remains compliant with relevant safety standards (such as EN 12941) and that the warranty and performance integrity of the ESAB system are preserved. This unit does not include the battery, charger, or filters, which are sold separately or transferred from the existing unit.

The motor is built with a durable, impact-resistant casing suitable for heavy industrial environments. It is sealed to prevent the ingress of welding dust and particulate matter into the electronics, although the air intake itself relies on the attached filters for protection. Regular testing of the motor's flow rate using a flow meter is recommended after installation to verify performance.
