How does laser fume extraction differ from solder fume extraction?

Laser processes produce finer particles and, depending on the material, more gases. Laser fume extractors therefore usually work with higher vacuum, multi-stage filtration up to H13 and an additional gas filter.

How much vacuum do I need?

It depends on hose length, nozzle and machine. Units in this category range from 1.900 Pa to 7.500 Pa, for example ULT LAS 0300.0 with 200 m³/h at 7.500 Pa.

What does H13 to DIN EN 1822 mean?

H13 is a HEPA filter class defined in DIN EN 1822. These filters separate fine particles from laser fume and dust before the air is returned to the room.

Can one unit serve several workstations?

Yes, there are units with higher air flow and ready-made sets such as the Weller fine dust extraction set with 190 m³/h for 2 workstations with Easy-Click.

When are cleanable filter cartridges worthwhile?

With heavy dust loads, cleanable cartridges extend service life, as in the ULT LAS 0300.0-HD.13 or the ULT LAS 0500.1 with cartridge filter.

Fume Extractions

Laser fume and fine dust extraction

This category covers fume extractors for laser fume and fine dust from laser marking, engraving and cutting as well as other dusty workstations. The range comes from Donaldson Bofa, ULT and Weller. Units start with compact models at 80 m³/h and 1.900 Pa and go up to the DustPro 1500 iQ with 1250 m³/h. The main differences are vacuum (up to 7.500 Pa), filter stages up to H13, gas filters for odours, and monitoring such as iQ control or a NOx sensor.

How to choose Laser fume and fine dust extraction

What matters when choosing: properties, comparison and typical applications.

Selection criteria

Criterion	What to check	Example from the range
Air flow	Size it by the number of extraction points and the capture method; several workstations need more air volume.	Weller Laser Line LL 400V with 645 m³/h
Vacuum	Long hoses, small nozzles and point extraction require high vacuum.	ULT LAS 0300.0 with 200 m³/h at 7.500 Pa
Particle filter	Laser fume is usually filtered with an H13 HEPA filter to DIN EN 1822.	ULT LAS 160 MD.11 SK, 4-stage filtration up to H13
Gas and odour filter	Plastics and coated materials call for an additional gas filter.	Weller Zero Smog TL with gas filter
Dust load	With heavy dust, choose cleanable filter cartridges instead of plain replacement filters.	ULT LAS 0300.0-HD.13 with cleanable filter cartridges
Monitoring	Have filter status and air flow controlled and displayed automatically.	Donaldson Bofa AD 350 with NOx sensor
