36x24 Laminar Flow Hood (Custom Built 2-3 weeks to ship)

Sorry, this item has sold.

Our 36”x24” custom built-to-order laminar flow hood is perfect for serious bag production. This model features a 36” x 24” x 6” 99.99 to .3 microns HEPA filter. The flow hood is powered by a Fasco centrifugal blower and includes a pre-filter. The unit is constructed from half-inch cabinet-grade birch plywood (no formaldehyde or VOC) cut using lapped miter routers that create self-indexing joints. This improved construction process provides more surface area for adhesion resulting in a superior bond and airtight construction. The cabinet has two coats of low VOC water-based polyurethane finish creating a low maintenance surface. The HEPA filter is protected by an aluminum grill. The grill can be removed for easy replacement of the filter when the time comes, typically after five years of average use. Overall dimensions are 37”x20”x38”. It comes fully assembled, ready to plug and play thanks to the top-mounted switch.

PLEASE NOTE: Due to the size and weight of the cabinet, the shipping cost listed is an estimate to ship from North Carolina to Chicago and is for comparison only. ACTUAL SHIPPING COSTS WILL DEPEND ON PURCHASER’S LOCATION.

Ideal for mycology/mushroom hobbyists, plant cultivators, and small-scale production. The larger size makes it ideal for bag cultivation.

Amazing product. Wonderful man who is so helpful and kind. Answered all my questions perfectly and communicated quickly. Would 100% recommend to anyone looking for a quality flowhood.


Just got my flow hood and I couldn’t be any happier. The build quality is excellent! The shipping packaging was excellent! The delivery tracking was detailed with daily updates on where the package was. Cougar was even nice enough to hold off on shipping it for a week, at my request, so that I could be home when it was delivered. Thank you guys so much for being so awesome! Absolutely beautiful, my friends are all jealous.


This flow hood is solid, and beautiful. The owners are very conscientous and work hard to earn your business. I would buy from them again and again. I am so looking forward to using it. I learned the hard way a 12" airflow for $400 is basically useless. The standard mycology bags won't even fit under a 12" flow.


Great workmanship. However, would recommend relocating the switch to the front instead of the top. I had to tie a stick to the switch so I could reach it.


This flow hood arrived safely and in perfect condition 🙌 Thanks to Phenomenal Fungi for excellent craftsmanship, attention to detail, good communication, and excellent value! I am excited to get back to the lab!
