Tecmen Pre-Filter Norway – Suits PAPR FreFlow V1 / V3 | Genuine Tecmen Spare Part

The Tecmen Pre-Filter Norway is the first-stage protective filter for the Tecmen PAPR FreFlow V1 and V3 blower systems. It captures coarse dust, metal debris, grinding residue and airborne particles before they reach the main P3 particle filter. Because the main filter must remain clean for stable airflow, the pre-filter significantly extends its service life and ensures consistent respiratory protection in industrial environments.

This pre-filter is a genuine Tecmen component designed specifically for welding, fabrication, maintenance work and metal processing tasks.

Function and Application

The Tecmen Pre-Filter performs an essential role in the air-filtration system:

• It blocks coarse contaminants before they reach the P3 filter.

• It maintains a stable airflow throughout long shifts.

• It reduces filter load, which increases battery efficiency.

• It improves the performance of the entire PAPR system.

As a result, welders experience cleaner air and longer intervals between P3 filter replacements.

Key Features

• Genuine Tecmen pre-filter for FreFlow V1 and V3

• First-stage protection for the PAPR unit

• Captures dust, metal particles and coarse airborne debris

• Extends P3 main filter lifespan

• Maintains stable airflow and blower efficiency

• Simple and fast replacement

• Lightweight and low-resistance material

• Suitable for welding, grinding, cutting and fabrication environments

Each feature supports consistent respiratory protection in demanding industrial conditions.

Technical Specifications

• Filter type: Pre-filter (coarse particulate filtration)

• System compatibility:
  – Tecmen PAPR FreFlow V1
  – Tecmen PAPR FreFlow V3

• Installation position:
  – Mounted in front of the P3 main filter

• Performance: Reduces particle load on the P3 stage

• Use case: Welding, grinding, metal fabrication, dust-heavy areas

This configuration helps stabilize the airflow at both 170 l/min and 210 l/min blower settings.

When to Replace the Pre-Filter

Replace the pre-filter when you notice:

• visible dust accumulation

• reduced airflow

• longer blower response time

• increased noise from the PAPR unit

• any signs of tearing, moisture or oil contamination

Replacing the pre-filter on time protects the main P3 filter and ensures proper air delivery.

Installation

1. Open the filter compartment of the PAPR FreFlow unit.

2. Remove the used pre-filter.

3. Place the new Tecmen Pre-Filter securely on top of the P3 filter.

4. Close the filter cover and check airflow.

The process takes only a few seconds and requires no tools.
