Husqvarna DE 120 vacuum extractor operator's guide

1

Hose connection and diameter selection

  • Attach an antistatic hose (38–51 mm recommended) to the inlet.
  • Select the correct hose diameter on the HMI.
  • Confirm the selection to prevent alarms and ensure proper airflow above 20 m/s for laser dust capture.
2

Power-up, e-flow, and operation

  • Press On/Off or select auto mode.
  • Activate e-flow for automatic optimization and energy savings.
  • Monitor the HMI during laser cleaning.
  • Maintain steady suction while adjusting as needed for the dust load.
3

Jet-pulse filter cleaning

  • When the alarm sounds, block the intake hose.
  • Press the purge button 3–5 times with 5-second intervals.
  • Restore suction without opening the unit. Perform more frequently for heavy masonry or metal oxide dust.
4

Alarm and warning response

  • Red alarm: stop work, purge filter, check hose, or empty Longopac.
  • Yellow alarm: plan HEPA service soon.
  • Always resolve before resuming laser cleaning operations.
5

Emptying the Longopac bag

  • Pull the full bag downward.
  • Add a second cable tie 10 cm below the first.
  • Cut between the ties.
  • Dispose of contents per local hazardous dust regulations.
6

Pairing with laser cleaning systems

  • Connect the antistatic hose directly to the Kamino 300 or similar unit.
  • Select appropriate diameter and activate e-flow.
  • Maintain airflow above 20 m/s for complete capture of fines and fumes.
7

Common troubleshooting

  • Low suction: purge filter and inspect hose.
  • Persistent red alarm: rinse pre-filter or replace HEPA.
  • Fiber or dust clog: empty Longopac and clean as needed.

FAQ

What is the Husqvarna DE 120 dust extractor?

The Husqvarna DE 120 is a professional HEPA-rated dust extractor designed for high-performance capture of fine and hazardous dust generated during laser cleaning operations.

What are the key features of the Husqvarna DE 120?

Key features include powerful suction with e-flow technology, jet-pulse filter cleaning, Longopac dust bag system, HEPA filtration, and HMI control for hose diameter selection. It maintains high airflow (>20 m/s) critical for effective laser fume and dust capture.

How do you operate the DE 120 with laser cleaning systems?

Connect an antistatic hose (38–51 mm) directly to the laser tool (e.g., Kamino-300), select the correct hose diameter on the HMI, activate e-flow, and monitor alarms. Use jet-pulse cleaning when the filter alarm sounds to maintain performance.

How do you maintain and empty the Husqvarna DE 120?

Perform regular jet-pulse filter cleaning, inspect hoses, and empty the Longopac bag using the double cable-tie method when full. Rinse pre-filters and replace HEPA filters as needed according to alarms and usage.

Why is the DE 120 important for laser cleaning safety?

It captures hazardous fine particles, metallic fumes, and coating residues at the source, protecting operators and the environment. Proper use helps maintain compliance with OSHA, Cal/OSHA, and local air quality regulations.
