A recent pharmaceutical cleanroom project required a reliable high speed roll up door for clean room applications, where sealing performance, anti-static materials, safe operation, and a flush installation structure were all important. For this project, AstraZeneca Pharmaceutical in China selected 4 sets of zipper high speed doors for a cleanroom area, helping improve controlled access between production-related spaces while supporting cleaner, safer, and more efficient daily operation.
Project Background
Pharmaceutical production areas usually have strict requirements for hygiene, personnel flow, equipment safety, and environmental stability. In cleanroom or semi-cleanroom areas, doors are not only used for access control; they also affect air leakage, dust entry, pressure balance, and cross-contamination control.
In this project, the customer needed a door solution for a cleanroom area inside a pharmaceutical facility. The door had to open and close quickly, maintain good sealing around the opening, reduce unnecessary air exchange, and avoid structural protrusions that could collect dust or interfere with cleanroom operation. Based on these requirements, SEPPES provided a customized high speed roll up door for clean room solution using zipper self-repairing technology and cleanroom-oriented details.
Project Configuration
The project included 4 sets of cleanroom zipper high speed roll up doors. The main configuration was designed around safety, sealing, and clean appearance.
Each door was equipped with a 2.5 mm anti-static PVC curtain. Compared with ordinary PVC curtain material, anti-static material is more suitable for pharmaceutical, electronics, laboratory, and precision manufacturing environments, where static control can help reduce dust attraction and protect sensitive processes.
For safety protection, each door was equipped with 3 pairs of photoelectric sensors. This multi-point safety configuration helps detect people, carts, or equipment near the doorway during operation, reducing the risk of contact between the moving curtain and passing objects.
The door also used an inclined stainless steel cover on the upper structure. This design is especially suitable for cleanroom environments because the sloped surface helps reduce dust accumulation compared with a flat-top design. Stainless steel also provides better corrosion resistance and is easier to clean, which is important for pharmaceutical production areas.
Another important detail was the embedded control box. Instead of installing a protruding control cabinet on the wall surface, the control box was recessed into the wall, keeping the surrounding area flatter and cleaner. This helps reduce collision risk, improves the overall appearance of the cleanroom passage, and supports easier cleaning around the doorway.
Why Zipper High Speed Doors Fit Cleanroom Use
A zipper-type high speed roll up door for clean room is different from a traditional fast rolling door because the curtain edge is locked into the side guide by a zipper structure. This design improves sealing and stability during repeated opening and closing. When the curtain is accidentally impacted and comes out of the guide, the self-repairing system can guide the curtain back into position during the next operating cycle, reducing maintenance downtime.
For pharmaceutical facilities, this feature is practical. Cleanroom doors are often used frequently by staff, carts, and production equipment. Frequent traffic increases the possibility of accidental impact. A self-repairing zipper structure can help the customer reduce manual reset work and keep the doorway operating smoothly.
High-speed operation is another key advantage. In cleanroom areas, the longer a door remains open, the more air exchange can occur between two spaces. A fast door helps shorten the opening time and reduce the impact on the controlled environment. This is one reason why many pharmaceutical, food, electronics, and laboratory projects prefer high speed roll up doors instead of ordinary swing doors or slow industrial doors.
Cleanroom-Oriented Design Details
This project was not only about supplying standard doors. Several details were customized according to the cleanroom environment.
First, the anti-static curtain helps support cleaner operation by reducing static-related dust attraction. Second, the full zipper side sealing structure helps reduce gaps on both sides of the curtain. Third, the stainless steel cover provides a clean and durable surface. Fourth, the inclined top cover design reduces horizontal dust-collecting surfaces. Finally, the embedded control box keeps the wall surface smooth and minimizes protrusions inside the working area.
These details are small individually, but together they make the door more suitable for pharmaceutical cleanroom projects. For facilities that must maintain strict operating discipline, equipment selection should consider not only basic opening and closing functions, but also hygiene, safety, durability, and long-term maintenance convenience.
Project Value for the Customer
After installation, the 4 sets of zipper high speed doors provided a more efficient access solution for the cleanroom area. The doors helped improve passage efficiency, supported better sealing performance, and reduced potential dust accumulation points around the doorway.
From a safety perspective, the 3 pairs of photoelectric sensors provided multi-position protection during door operation. This is especially important in production environments where personnel and material carts may pass through frequently.
From a maintenance perspective, the zipper self-repairing structure can reduce downtime caused by accidental curtain derailment. For pharmaceutical plants, minimizing downtime is important because even small equipment interruptions may affect daily production flow.
From an environmental control perspective, the fast opening and closing speed helps reduce unnecessary air exchange between areas. While a door alone cannot determine the full performance of a cleanroom system, a properly selected high speed roll up door for clean room applications can support the overall cleanliness and pressure-control strategy of the facility.
SEPPES Experience in Pharmaceutical Door Projects
SEPPES has provided industrial door solutions for many industries, including pharmaceutical manufacturing, food processing, cold chain logistics, electronics, automotive, warehousing, and precision manufacturing. Different industries require different door structures. For cleanroom areas, sealing, hygiene, anti-static performance, and easy cleaning are usually more important. For logistics areas, opening speed and durability are often the priority. For cold rooms, insulation and temperature control become critical.
This project reflects SEPPES’ ability to customize door solutions according to real working conditions instead of only offering standard products. From curtain material and safety sensors to stainless steel covers and embedded control boxes, each configuration was selected to match the pharmaceutical cleanroom environment.
Conclusion
This AstraZeneca Pharmaceutical project shows how a customized high speed roll up door for clean room can support efficient, safe, and cleaner access control in pharmaceutical production areas. With 4 sets of zipper high speed doors, 2.5 mm anti-static curtains, 3 pairs of photoelectric sensors, inclined stainless steel covers, and embedded control boxes, the solution was designed to meet the practical needs of a cleanroom environment.
For pharmaceutical, medical device, food, electronics, and laboratory facilities, choosing the right door is not only about fast opening. It is about sealing performance, cleanroom compatibility, safety protection, maintenance efficiency, and long-term reliability. A well-designed high speed roll up door for clean room can become an important part of a controlled production environment.
