Description
Fine toxic powders and dense mineral dust blind small vacuum filters within thirty seconds of surface grinding. The Delfin Industrial DG 50 SEV402 (V404H) system mounts an oversized filtration chamber over an industrial side-channel blower for continuous heavy dust capture. Built for three-phase power grids, this continuous-duty extractor manages high dust loads, though its sheer physical height makes low-clearance transport impossible.
An extended upper filter housing encloses a massive antistatic polyester cartridge system that provides nearly double the surface area of standard industrial extractors. The side channel turbine features precision balanced die-cast aluminum internal stages that operate with zero internal friction, preventing mechanical wear over years of non-stop work. Heavy steel toggle clamps pull the filter dome tight against thick EPDM rubber gaskets, stopping fine dust leaks.
Oversized Filtration System Specs
Cement plants and bulk powder bagging lines produce massive particulate volumes that choke standard shop filters. This heavy three-phase extractor pairs high air volume with expansive filtration surface area.
- High Capacity 4 kW Side Channel Turbine runs 24 hours per day with zero mechanical maintenance.
- Enlarged Filter Housing Chamber accommodates high dust volumes without clogging primary airflow paths.
- Three-Phase 230/460 Volt Electrical Stator delivers relentless torque without thermal breaker trips.
- Class M Certified Star Filter with high surface area captures abrasive fines down to 1 micron.
- Manual Mechanical Filter Shaker quickly sheds heavy powder cakes without exposing workers to dust.
- Detachable 100-Liter Collection Bin rolls independently on heavy steel casters for clean dumping.
- Heavy Gauge Carbon Steel Construction withstands heavy impacts from aggressive forklift warehouse traffic.
Turbine Bench Run Heat Analytics
Dyno bench testing confirms 7.2 Amp draw at 460 Volts under maximum suction drag. Turbine casing heat stabilizes at 164°F in 72°F ambient shop testing after three hours of constant cycling. Suction instruments measure 142 inches of static water lift paired with 318 CFM open airflow. Sound monitoring tools record 76 dBA at 5 feet. Pressure differential gauges across the clean star filter indicate less than 2 inches of water drop.
Shop Deployment Fleet Limitations
Moving this tall tower unit requires smooth high-clearance doorways, and tip hazards increase when traversing rough yard transitions. Sandblasting plants and ceramic tile factories gain continuous run performance, but maintenance crews wanting quick transport in light pickup beds cannot load this massive 330-pound machine.
- Inspect internal housing EPDM gaskets every 60 days to stop fine particulate bypass leaks.
- Measure motor line current across all three legs every quarter to catch phase imbalance early.
- Cycle the external filter shaker mechanism vigorously before dropping the lower waste bin.
Factory Warranty Crate Inventory
Delfin supplies a 2-Year limited manufacturer warranty on the complete blower assembly and structural housing. The crate contains the DG 50 SEV402 vacuum machine, 100-liter collection bin, oversized star filter, 16-foot crushproof industrial hose, 2-inch steel double bend wand, heavy floor tool, and technical maintenance manual.
