Clean Room Contractor: What To Consider In Clean Room Construction
Your industry may require a sterile working environment for its manufacturing process. A clean room can provide the controlled enclosure you need. However, you have to hire a qualified cleanroom contractor to construct a contaminant-free facility without pitfalls. A professional can build an efficient controlled environment on a budget and on time.
The design of a clean room depends on its intended usage. Pharmaceutical industries require a sterile environment where experts produce medical devices and medications. An experienced cleanroom contractor will know the procedures, principles, and materials needed. Besides, the person has to consider specific factors to build an environmentally controlled facility.
Clean room design
The architectural specifications should allow laminar flow of air. The contractor should consider the size and location of openings such as windows and doors. Besides, the knowledge of the best materials for these structures will contribute to an efficient clean room. Restriction of air flow in such enclosure can lead to turbulence and eventually, particle movement. The design of a clean room should allow air to flow in a parallel pattern and with uniform velocity.
Humidity and temperature
It is vital to meet the humidity and temperature requirements for a clean room. Controlling the environmental factors will provide personal comfort for workers. Temperature control will create favorable conditions for instruments and materials. An efficient humidity monitor can eliminate condensation on work surfaces. It can also reduce corrosion and static electricity.
A contractor should prevent the infiltration of wind in a clean room. Keeping the atmospheric pressure below the static will make the condition possible. However, a negative pressure is necessary for working with hazardous materials.
The air volume required to maintain the quality of indoor air determines the ventilation of a clean room. The contractor should also consider the replacement of the process exhaust in the facility and pressurization.
HEPA (High-Efficiency Particulate Air Filter)
The location of the filters to the critical working areas is essential. The HEPA maintains a contamination-free environment by eliminating particles. It can even remove small contaminants of about 0.3 microns.
An experienced contractor will know the specifications required for the construction of a quality clean room. Analysis of factors such as temperature, humidity, pressure, air velocity and flow is necessary. Controlling these conditions will help eliminate particle contamination.
Electrostatic Discharge (ESD)
Electrical charges can cause damages in an environmentally controlled facility. These discharges may result from wind or friction between two surfaces. The use of ESD protective materials is vital for the prevention of damage from electrostatic charges.
The intended use of a clean room determines its required level of cleanliness. Besides, a cleanroom contractor should decide on the type and number of places needed depending on the manufacturing process. The capacity of the space is crucial to maintaining the workers’ comfort. The expert shouldn’t overlook the process requirements for liquid, gas, and electrical system. Besides the standard specification, the enclosure should satisfy the needs of the end user. A contamination-controlled room should provide a sterile environment for production processes.
