Tiger-Vac CD-25L EX DT (MFS)
The Tiger-Vac CD-25L EX DT (MFS) is the compact 25 L variant of the CD-MFS family -- marked II 1/2GD to EN 17348 DT (Z1-21), i.e. category 1/2 for dust and gas simultaneously. It shares motor, flow, cleaning system and filtration with the CD-36L (MFS) HEPA, but has a smaller tank and smaller footprint -- suited for space-constrained pharmaceutical or chemical process rooms where 36 L is not needed and mobility matters. Manual Filter Shaker (MFS) knocks dust cake off the primary filter manually, the detachable 25 L tank can be lifted off the cart for quick emptying, and the HEPA H14 final filter ensures fine particles do not escape in the exhaust. Three-phase TEFC motor at 2.2 kW is standard (single-phase 1.5 kW as option). The whole unit is IP65 rated.

Questions and answers
When should I choose 25 L over 36 L?
Choose 25 L when dust production is moderate and space constraint outweighs tank size. Rule of thumb: at 212 m3/h / 2540 mmH2O a 25 L tank fills with fine dust in 2-4 hours of continuous collection (depending on dust type). With coarse or heavy dust (metal chips, mineral powder) 25 L can fill in under 30 minutes. For continuous large production choose the 36 L variant (cd-36l-ex-dt-mfs-hepa) so you empty less often. For smaller tasks or supervised batch operation 25 L is ample and gives lower weight (85 kg versus 99 kg) and smaller footprint (70 cm length versus 78 cm). Motor, flow and cleaning system are identical -- only the tank and chassis dimensions are smaller.
What does Z1-21 in the model name mean?
Z1-21 is Tiger-Vac's usage note indicating the model is intended for Zone 1 (gas) and Zone 21 (dust). The actual ATEX marking is II 1/2GD -- category 1 internally (Zone 0/20) and category 2 externally (Zone 1/21). Zone 2 and Zone 22 are less strict and are covered automatically, so the model can also be used there without changing the certification. Z1-21 is thus a summary of the most demanding zones the model is designed for.
What is MFS, and why is it suited for this application class?
MFS (Manual Filter Shaker) is a mechanical shaker system for the primary filter. The operator activates a lever on the side of the filter housing that shakes the filter so the dust cake falls into the tank. The benefit is simplicity -- no electronic valves, no compressed air supply, no timers requiring separate ATEX certification. This keeps overall system certification simple and maintenance low. MFS works best with dry, heavier dust types that release naturally from the filter surface. For fine, sticky dust types Manual Reverse Purge (MRP) can be more effective -- that variant is available on the CD-36L MRP ULPA model.
Can it pick up liquids?
No. The CD-25L EX DT (MFS) is dry-only -- EN 17348 DT. For wet/dry in the same II 1/2GD class choose the Delfin 802 WD AIREX 1/2D-2/2G.
How quiet can operation be expected?
Sound level is specified as 72 dB(A) at 1 metre distance under normal operation with the standard three-phase TEFC motor and HEPA filter. This corresponds to a medium-high vacuum sound level -- audible but not disruptive in an industrial environment. The RE muffler assembly (stainless steel with sound-insulating foam) that is included reduces exhaust noise significantly. With the single-phase motor (option) sound level may be slightly higher due to higher current draw and motor vibration. Hearing protection is recommended for sustained work above 85 dB(A) -- not reached under normal operation of this unit.
What is the difference from CD-230V EX MRPFT HEPA?
Both are II 1/2GD. Differences: CD-25L is MOBILE on a cart with conductive wheels, 25 L detachable tank, MFS cleaning, single- OR three-phase TEFC motor. CD-230V is STATIONARY (in practice) with 50 L fixed tank, MRPFT cleaning (Manual Reverse Purge with Filter Tubes, a bag-less variant with filter tubes instead of cartridge) and ONLY single-phase TEFC motor. Choose CD-25L if the task is mobile and dust loads are moderate. Choose CD-230V MRPFT if the task is permanently close-coupled to process equipment with large flow demand.
