Dust extractors – HTC D10, D20, D30
The HTC D10 is a light and versatile dust extractor, best suited for handheld grinders and general clean-up. It’s equipped with the HEPA H13 filter and has a pressure gauge that indicates when the filter is clogged.
The HTC D20 recommended for HTC 280 and 450. With two HEPA H13 filters, it can handle the finest concrete dust. The machine is easy to use with puncture-proof tires and locks on the front wheels. It’s also equipped with time counter.
The HTC D30 is a very powerful, single-phase dust extractor with three large vacuum motors. Three HEPA H13 filters, as well as a conical filter with a 4.5 m² filter surface, enables the HTC D30 to effectively collect both coarse and fine dust. It’s also equipped with time counter.
The 3 models are equipped with a vacuum gauge and a Longopac® system for safe handling of dust.
What does the H-Classification mean?
The international standard for testing dust and water extractors (IEC-60335-2-69, EN-60335-2-69) encompasses three classes – L for low, M for medium and H for high – with the H class being the most stringent (do not confuse this “H” with the one in HEPA H13). HTC D10, D20 and D30 are H classified.
What is a HEPA H13 Filter?
HEPA (High Efficiency Particulate Air) is a highly efficient particle filter for air. The stringent HEPA standard (EN 1822-1) is divided into different levels (E10 to H14) depending on the filter efficiency. HTC uses level H13, which can separate up to 99.95% of the particles in sizes 0.15 to 0.30 μm. These particle sizes are the most difficult to separate – both larger and smaller particles are easier to catch in a filter. Besides this, HTC tests each individual filter prior to delivery to ensure that they comply with the HEPA H13 standard.
3-step filtration for your safety
- The cyclone separates the largest particles, which go to the Longopac bags.
- The prefilter (conical filter) handles the finer dust that is not separated in the whirler.
- Lastly, the air passes through a certified HEPA H13 filter that separates 99.95% of the smallest and most dangerous particles.
