Frequently Asked Questions:

  • FAQ 1: What is the difference between a hardwall and softwall cleanroom?

    Like the name suggests, hardwall modular cleanrooms use rigid, interlocking panels to create a free-standing structure. These are typically used in small-to-medium sized operations requiring stricter pressure, temperature, and humidity control or in applications requiring superior cleanliness, but at significantly greater cost and time.

    Softwall cleanrooms are a canopy-like structure utilizing flexible wall materials (typically vinyl curtains) fixed to a metal frame. Low-cost, lightweight, portable, and durable enough for demanding manufacturing processes, softwall cleanrooms are quickly becoming the ideal solution for a range of applications.

  • FAQ 2: How soon can I expect delivery of my softwall cleanroom?

    Before manufacturing begins, our engineers will meet with your design team to discuss your specific design requirements. Depending on the complexity of your specific application, a set of plans will be drafted for your final approval in 2 to 4 weeks. Once your team has given final approval on design, manufacturing will take 2 to 8 weeks depending on the size of your application.

    From initial discussion to approved drawings, manufacturing, and packaging, most orders are generally ready for shipping within 6 weeks. Depending on your location, shipping can take an additional 4 to 6 weeks.

  • FAQ 3: Is there an option for delivery and installation?

    Though our softwall cleanrooms are easy to assemble with basic tools, Pacific Environmental Technologies also offers delivery & installation services at additional cost for hassle-free deployment and testing at your facility. The additional cost of this is subject to the size of your cleanroom, any additional shipping expenses, and your distance from us. Speak with one of our sales or design engineers for additional information.
