상품 소개

The 400 mm cubic chamber is the smallest active-airflow model in this batch. A 0.2 kW package delivers a rated 0.45 m/s plus or minus 20% unidirectional flow inside a fully welded SUS304 or SUS316L enclosure. Twin 6 W UV lamps and a selectable mechanical or electronic interlock support controlled small-batch transfers where a passive hatch would not provide an active purge.

주요 기능

Small-volume active purge

The compact cube concentrates filtered airflow around sealed samples and tools without powering an oversized chamber.

Low connected duty

The 0.2 kW electrical package fits small transfer points while retaining positive-pressure air treatment.

Cleanable welded interior

Fully welded stainless construction and integrated curved corners reduce joints within the working area.

Applications

For sealed vials, tools and small component packs moving between adjacent pharmaceutical, biotechnology, API or quality-control rooms. Buyers should compare the load's true diagonal clearance against the 400 mm cube and reserve vertical space for the active-air package above the work chamber.

Solutions for Your Application

A passive pass box does not purge loose particles before the receiving door opens.Use the HEPA-filtered positive-pressure airflow and a defined closed-door purge interval before retrieval.

A full-size dynamic chamber wastes wall and service space for sample-scale transfers.Select the 400 mm cube and 0.2 kW package when every qualified load fits its opening and work zone.

사용 가능한 옵션

Choose SUS304 or SUS316L, mechanical or electronic interlocking, automatic or manual operation and alternate door arrangements. Validate UV exposure suitability for the actual materials; the lamps do not replace the site's approved cleaning process.
