Lincoln Miniflex Portable Welding Fume Extractor

The Lincoln Miniflex Portable Welding Fume Extractor is a portable and effective solution for the removal and filtration of welding fumes in confined and other hard to reach spaces. Unlike other bulkier welding fume extractors, the Miniflex leads the industry in portability and ease of use. The Miniflex is a high vacuum system designed for the removal and filtration of welding fumes from light duty welding applications.

  • Current Sensor - Allows convenient automatic start/stop capability by sending welding current.
  • Multiple Extraction Settings - Choose extraction capacity setting based on environmental conditions 94 CFM (Low) or 135 CFM (High).
  • Quiet Operation - Operates at a sound level of less than 70dB(A).
  • Carbon Brushes Early Warning System - Alerts the user when 80% of the carbon brushes have been consumed.
  • System Airflow Check - Allows the user to check the extraction performance of the unit.
  • Wall Mounting Bracket (K2389-7) - Allows the Miniflex to be mounted on a wall, freeing up valuable floor space.

The Miniflex is ideal for use by contractors, maintenance workers, small to medium fabrication shops, and home hobbyists.

  • Cleaner Work Environment - Reduces fumes and particulate in the operator and surrounding work areas.
  • Easy to Maintain - Quick disassembly for cleaning and filter replacement.
  • Light Weight - Ease of portability and placement in work areas.
  • Low Noise Level - Will not contribute to increased noise levels.
  • Economical to Operate - Start/Stop sensors reduce energy consumption.

Lincoln Miniflex Portable Welding Fume Extractor What's Included

  • 9 ft. (2.7 m) cord (AWG 14) with 15 amp plug (NEMA 5-15).
  • 8 ft. (2.4 m) length x 1-3/4 in. (45 mm) O.D. extraction hose.
  • LongLife-H main filter.
  • HEPA filter.
  • 2 spare sets of carbon brushes and seals for motors.

The Miniflex Five-Stage Filtration Process

Stage 1: Air passes trhough a removable and washable pre-filter where heavier particles and foreign material are captured in the collection tray.
Stage 2: Air passes through a second pre-separator to further reduce medium to heavy particulate matter.
Stage 3: Air passes through the LongLife-H filter where welding fume particles are captured and deposited.
Stage 4: Activated carbon filter (optional) will help prevent or neutralize the release of odors back into the environment.
Stage 5: Final filtration as air passes through the HEPA H12 Class Filter.

Miniflex Five-Stage Filtration Process

A. Stage 1: Pre-filter (KP2390-3) captures larger particles and drops particulate matter into collection tray.
B. Stage 2: Pre-Separator captures medium to heavy particulate matter.
C. Stage 3: LongLife-H Filter (KP2390-1)
D. Stage 4: Activated carbon filter (K2389-1) (Optional)
E. Stage 5: HEPA H12 Class Filter (KP2390-2) for higher filtration efficiency.
F. Automatic Start/Stop for less energy consumption and convenience
G. Smart noise insulator
H. Wheels are standard for easy portability
I. Intake connection for extraction hose
J. Current sensor cable tray/groove
K. Two motors for better extraction performance
