"Orders are scheduled until next month, and stopping production for renovation would mean a loss of over 50,000 per day!" This is a common concern for industries like pharmaceuticals and electronics when upgrading cleanrooms. Traditional renovation methods often take months, putting companies in a dilemma. However, a renovation solution centered on FFUs (Fan Filter Units) enables "simultaneous production and renovation." As an FFU manufacturer, Zhongjing Purification details a practical three-phase implementation strategy based on hands-on case studies.

I. Pre-Renovation: Leveraging FFU Characteristics to Avoid Production Stoppage

Scientific planning is the foundation of non-stop production renovation, and the flexibility of FFUs provides the necessary support. During joint surveys by engineering and production teams, the advantage of FFUs—"no need for large-scale ceiling renovation"—can be utilized to divide the workshop into zones: use laser rangefinders to determine installation points, particle counters to measure baseline cleanliness, and match filtration levels according to process requirements.

By leveraging FFU adaptability, zones are divided into "production retention areas" and "renovation construction areas." After partitioning with fire-resistant color steel plates, pre-install FFU mounting tracks in the construction area without占用 production time.

II. During Renovation: Achieving Zero Production Stoppage with FFU Modular Construction

Modular construction is key, with FFUs serving as the core equipment. For floor renovation using the "local grinding + thin-layer epoxy" method, temporary mobile FFUs are deployed in corresponding areas to meet purification needs. Each area is completed within 48 hours, and production resumes 24 hours after FFUs are installed and fixed.

For core equipment that cannot be moved, the "FFU + anti-static curtain" solution is adopted: the curtains create a temporary clean space, with built-in FFUs generating localized clean airflow. The outlet wind speed is stabilized at 0.45m/s ±20%, ensuring compliance with cleanliness standards around the equipment during renovation.

III. Post-Renovation: Ensuring a Smooth Transition with FFU Stability

A smooth transition after renovation is critical, and the stability of FFUs plays a central role. Implement an "acceptance during renovation" mechanism: after FFU installation in each area, use anemometers to check air supply speed and particle counters to verify filtration efficiency before proceeding to the next zone.

After acceptance, adopt a "gradual switchover" approach: initially operate FFUs in one production line area for 3-5 cycles to observe filtration capability and compatibility. Once product qualification rates show no fluctuations, deploy FFUs in batches.

The flexibility, modularity, and stability of FFUs are key to non-stop renovation of old workshops. Zhongjing Purification offers FFU products and renovation solutions tailored to various scenarios. For details on selection parameters or case studies, contact our professional team.
