Mirror stainless steel box

According to the project requirements, Aili Industrial snap-on EFU can use SUS304 mirror stainless steel box.

Stainless steel materials are suitable for application environments that have corresponding requirements for equipment materials, surface cleaning and daily maintenance.

The box material and surface treatment can also be configured according to specific project conditions.


Can be configured according to the project

SUS304 stainless steel/SUS316 stainless steel/other metal materials/different surface treatments


Specific materials need to be determined based on the use environment, cleaning methods and project technical requirements.

Integrated design of fan and high-efficiency filter

The snap-on EFU integrates the fan and high-efficiency filter into the equipment box.

When the equipment is running, the fan drives the air into the interior of the EFU. After the air is filtered by the high-efficiency filter, it is sent from the air outlet side into the interior of the equipment or the target clean area.

Working principle

Air entering → Fan drive → Air flow organization → HEPA/ULPA filtration → Clean air sent out

The specific airflow organization method is determined based on the EFU structure, fan configuration and equipment installation conditions.

Designed for equipment-side clean air needs

EFU extends clean air supply directly to equipment


In semiconductor, photovoltaic, lithium battery, panel display and electronic manufacturing equipment, some key areas require a stable and clean air environment.


Unlike relying solely on centralized clean room air systems, EFU can be installed directly inside or at the equipment end to provide local clean air to the target area.


Aili Industrial EFU integrates fans, motors, filters and control systems into a compact structure and matches them according to equipment space and actual process requirements.


Instead of simply reducing the FFU, the structure and aerodynamic design are redesigned for equipment-side applications.
