2. Secondary Electrostatic Primary Filter Cotton : Extra-large 2100 cm² Filtering area, washable, filtration 4μm Dust efficiency 99.5% , ensuring sustained, stable high airflow and resistance to clogging Nilfisk 。
3. Optional HEPA High-efficiency filter : Yes 0.3 μm Particulate filtration efficiency 99.97% , compatible Class100 Class 100 Cleanroom Standard Liqi Weiba 。
4. Optional ULPA Ultra-efficient filter ： 0.12 μm Granule 99.9995% Filtration, suitable for higher‑grade cleanrooms; optional accessories are also available. PTFE Anti-adhesive, Nomex High-temperature‑ and acid‑/alkali‑resistant specialty filter media, designed to handle special dusts and corrosive airborne particulates. y38.up71.c...。

The entire unit is certified to Class L for dust, ensuring that the exhaust air does not re‑contaminate the cleanroom and can also handle hazardous asbestos‑containing dust. Nilfisk 。

II. The body is durable, lightweight, and user-friendly for cleanroom applications.

1. Aluminum alloy barrel body : The entire machine only 5kg It is lightweight yet impact‑resistant and corrosion‑proof, with minimal flaking, meeting the dust‑free workshop requirement of no particle generation. It boasts a long service life and is well suited for prolonged, high‑frequency operations. Nilfisk 。
2. Mobile and convenient : Matching steel trolley + Large rubber silent wheels; when rolled across cleanroom floors, they leave no scratches. 10  Equipped with a long power cord, it offers a wide operating radius, so you won’t have to keep switching outlets.
3. 1200W Professional motor Vacuum degree 20kPa , airflow volume 38L/s , with strong and stable suction; operating noise is only 61 decibel , Low-noise nighttime operations in workshops and laboratories ensure no disruption to production or experiments.
4. Flexible to use : Support Dust bag usage / Bagless direct suction Two modes; 9 12L Dust capacity meets the daily cleaning needs of small to medium-sized clean areas. Nilfisk 。

III. Wide Industry Compatibility and a Comprehensive Parts Ecosystem

Applicable Scenarios : Pharmaceutical GMP workshops, semiconductor electronics cleanrooms, food-grade clean facilities, physicochemical laboratories, hospital operating rooms, and precision optical workshops; it can also be used in environments handling small amounts of hazardous or specialized dust.

• Complete set of factory‑original, dedicated nozzles, hoses, and metal connectors, compatible with a variety of application scenarios—crevices, countertops, floors, and more.
• The market for filter‑media components is sizable, with convenient aftermarket procurement and replacement, and a well‑established after‑sales service system.

IV. Key Differences Compared to Standard Industrial Vacuum Cleaners

Conventional vacuum cleaners feature only a basic two-stage filtration system, and their exhaust air can blow fine particulates back into the atmosphere, compromising the cleanroom’s cleanliness class. The GM80P, on the other hand, incorporates a rear-mounted HEPA/ULPA terminal filter. Filtration is performed at the exhaust end. After vacuuming, it exhausts clean air, thereby preventing secondary pollution and meeting the acceptance and operational requirements for cleanrooms.
