DOT-LEM35 Laser Engraving System
DOT-LEM35 Laser Engraving Machine

With the DOT-LEM35 Laser Engraving Machine, engraving,
cutting and marking has evolved from a difficult process to an
easy task. Just Plug and Go!

Easy to Operate
Whether you want to engrave, cut or mark, the DOT-LEM35 is
easy to use, precise, fast and reliable and is ideal for an expert
engraver or a first time user.

The DOT-LEM35 comes supplied as a complete, ready to use package.
You simply unpack it, follow the installation instructions and start engraving.
Easy to Use
The DOT-LEM35 is supplied with a laptop pre-loaded with the printer driver and both DOTlabel Software and the Graphic Engraving Software.

Easy to Maintain
The DOT-LEM35 was designed with ease of maintenance in mind and the optics and
worktable can be removed for cleaning and reinstalled quickly and easily.

Standard Features

equipped with a visible “red dot” pointer for quick and easy positional alignment.

LCD Control Panel - Easy to understand instructions and ergonomically designed LCD
Control Panel enhances efficiencies and productivity.

DOT-LEM35 Laser Fume Extraction System

The DOT-LEM35 laser fume extraction and purification system has been designed as a low cost, yet fully comprehensive unit. This compact and extremely quiet system is ideal for use in sign making workshops, industrial environments and light laser coding applications.

Pre Filter
The pre filter used in the DOT-LEM35 has an efficiency of 95%. This offers maximum protection for the more expensive combined HEPA and gas filter.

HEPA Filter
All HEPA filters are manufactured by specialist filter companies to our specification. This ensures that the latest manufacturing and testing techniques are used. Each filter incorporates a series of bonded webbing between the pleats. This feature not only guarantees even spacing between each pleat, but also alleviates the possibility of airflow vibration or collapse. Filters are individually tested and certified to a minimum efficiency of 99.997% down to 0.3 microns and 95% as small as 0.1 microns. Test certificates are available on request.

Chemical / Gas Filter
The standard chemical filter contains a multi-purpose media to give protection against a range of volatile organic compounds generated when lasering polymers (plastics) and other organic materials.

Filter Replacement
Filters can be replaced quickly, with ease and safety. Each new filter comes with a resilient neoprene gasket fitted. This ensures that there is no filter bypass caused through reusing existing potentially torn or perished built in seals.

Unit & Filter Monitoring System
Each unit is fitted with a continuous monitoring system of 3 coloured LED’s, which tell the user of the condition of filters within the system. Green indicates that the filters are clean, amber when filters are getting close to replacement and red when the filters are blocked and requiring changing. The green LED also indicates that the unit is running and all 3 LED’s will flash if there is a fault within the system.
