Driving Fan

The T3 is equipped with high-quality motor fans: high efficiency, large air volume and high negative pressure. Three motors are built inside the machine cap, each with its own independent switch, so suction and air volume can be matched to the job. The cap is integrally moulded plastic — lighter and durable.
Efficient Purification

The T3 is equipped with a PTFE-coated filter cartridge: filtration efficiency above 99% for dust at 0.3 μm, so the air leaving the machine is clean.
Refuse to Block

Dust builds up on any cartridge. The T3 cleans it with blowback vibration dust cleaning — the JF503 adds electric vibration — so dust falls off the cartridge surface and ventilation — and suction — stays effective.
Continuous Bagging Structure

A long transparent plastic bag is folded and fixed on the machine. Pull the bag out as dust collects, tie it off where you want, cut it, and keep working — easy loading, unloading and transport.
Mobile Equipment, Less Effort

Universal brake wheels plus directional wheels: flexible steering, stable walking, easy to move even when the bucket is full.
Professional Accessories, Matching Use

A set of professional D50 standard accessories is included: S-shaped elbow, vacuum floor brush and wear-resistant hose. The D70 aluminium die-cast suction nozzle is compatible with D40 and D50 vacuum kits.
