Safe Change filter housing for industrial safety applications
Safe Change filter housings from Hengst enable contamination-free filter changes in safety-critical applications. With the MultiSafe Safe Change filter housing, Hengst offers a specially developed solution for areas where the highest demands are placed on tightness, containment and operational safety.
Safe HEPA filter change to protect employees and the environment
In safety-critical applications, it is not only the filtration itself that is crucial, but also the controlled replacement of the Filter Elements. A Safe Change filter housing ensures that the filter is changed under defined containment conditions and that no contaminated particles are released into the environment.
The Hengst MultiSafe Safe Change filter housing is gas-tight and designed for applications in which even minimal emissions are intolerable. Thanks to the integrated bag-in/bag-out process, the contaminated filter element remains completely enclosed during the entire change process. This reduces the risk of exposure for employees and supports controlled operation, even in sensitive areas.
Benefits & added value for people, the environment and operations
The use of a Safe Change filter housing offers decisive benefits in safety-critical applications. The focus is not only on filtration, but also on safe and controlled filter replacement as an integral part of a holistic safety concept.
With the MultiSafe system, Hengst is pursuing a systematic approach: housing design, replacement procedure and testability are coordinated with each other and form a robust solution for demanding areas of application.
Protecting the health of employees
When changing contaminated filters, there is an increased risk of exposure without suitable protective measures. The MultiSafe Safe Change filter housing enables a closed change process in which contaminated Filter Elements remain safely enclosed.
The combination of welded housing construction, defined sealing fit and integrated change procedure supports the controlled performance of maintenance work in sensitive areas.
Avoiding emissions and protecting the general public
In applications with increased hazard potential, the prevention of uncontrolled emissions is a central component of the safety concept. The MultiSafe system supports this goal with a tested tightness concept and a structurally safe housing design. This reduces the risk of hazardous particles being released, even during maintenance processes.
Increased operational safety
Controlled filter changes make a significant contribution to the stability and reliability of systems. The MultiSafe Safe Change filter housing is designed as a robust, modular solution and enables structured integration into existing systems.
This supports a long-term stable system configuration.
Application-specific adaptation
Safety requirements differ depending on the industry and potential hazards. The MultiSafe system is therefore flexibly configurable and can be adapted to different filter stages, material requirements and project-specific conditions. Hengst supports this process with technical expertise and application-specific design.

Safe Change filter housing for the highest safety requirements
With the MultiSafe Safe Change filter housing, Hengst offers a specially developed solution for applications in which the filter change itself is a safety-critical process.
The focus is on a consistent containment concept: the system is gas-tight and designed to ensure freedom from contamination not only during operation but also during maintenance.
The filter is changed using an integrated bag-in/bag-out process. The contaminated Filter Elements remain completely enclosed during the entire change process. In addition, the system enables verifiable filter sealing and thus supports technically traceable quality assurance.
The modular concept allows flexible integration of different filter stages and application-specific design. This makes the MultiSafe Safe Change filter housing suitable for demanding industrial environments in which tightness, operational safety and systematic risk minimization are paramount.
Typical areas of application for Safe Change HEPA filters
Safe Change filter housings are used wherever the filter change itself must be regarded as a safety-critical process.

Frequently asked questions about Safe Change filters
What legal and normative requirements apply to safe change filters?
The requirements for Safe Change filter housings are determined by the respective application and the specific hazard potential. Different safety and regulatory requirements apply depending on the industry.
How does a Safe Change filter housing differ from a conventional filter housing?
The difference lies in the extremely high tightness of the housing and the replacement procedure. While conventional housings are changed openly, a Safe Change filter housing enables closed replacement under defined containment conditions. This reduces the risk of exposure to contaminated filter media.
Is a Safe Change filter housing required for every HEPA filter?
No. The use of a safe change system does not depend solely on the filter class. The decisive factor is whether there is a relevant risk from contaminated particles or substances when changing the filter. The assessment is based on the application.
What criteria need to be considered when designing a Safe Change filter housing?
Key parameters include Air flow, differential pressure, filter class, installation situation and industry-specific safety requirements. These factors determine the technical configuration of the system.
Can a Safe Change filter housing be integrated into existing systems?
Integration into existing ventilation or exhaust air systems is generally possible, provided that the technical framework conditions are taken into account. These include space conditions, air routing and safety requirements. Project-specific testing is required.
How is the tightness of a Safe Change filter housing checked?
Tightness is ensured within the frame of defined test procedures. Depending on the application, different testing and measuring concepts are used to verify the requirements for housing and filter seat.
