Glove box clean room

thingiverse

This is my latest project, which remains in the development phase. The idea is to create a completely sterile environment. This can be suitable for various uses. For example, opening a hard drive, working with lasers and camera lenses, or in my case, reviewing an oxygen pure regulator. ## Current state: - I have redesigned all components again and some of them are already printed. ## My requirements: - A room as clean as possible - A slight negative pressure is to be produced - As little noise as possible - Fan control via PWM signal would be desirable - Possibly a backwater flap - Enough space to assemble a regulator - A compressed air connection for an air pistol inside and an inflator nipple on the outside for connecting a medium-pressure hose. - Possibly an LED light strip - The gloves should be changeable in the room - The sight glass should be as transparent as possible, therefore a cutout with highly transparent acrylic glass may be necessary. ## Concept & Material: The links below are partly parts I bought myself, but also parts I would recommend to someone else instead. All items are for demonstration purposes. Surely the listed articles are also available at a lower price. - For quiet and strong air exchange, I decided to use the Noctua NF-A12x15 PWM. A flat 120mm fan with a volume flow of 94.2 m³/h ensures sufficient air exchange. https://www.amazon.com/dp/B071W6HJP6/?coliid=I1EBS3CXAG77S2&colid=2KFUAVHU5UKJ2&psc=0&ref_=lv_ov_lig_dp_it - Interchangeable HEPA filter https://www.ebay.com/itm/RV-Vacuum-Cleaner-Replacement-HEPA-Filter-for-karcher-DS6000-DS5600-DS5800-Gw-/113832849765?hash=item1a80f77165 - Pneumatic compressed air coupling with 3/8" female thread https://de.aliexpress.com/item/2-Pc-Pneumatische-Teile-Euro-Air-Linie-Schlauch-Kompressor-Quick-Release-3-8-BSP-Innengewinde-Koppler/32835468090.html?spm=a2g0s.9042311.0.0.4fbf4c4dYuZuiM - 110mm Silicon arm cuff from diving https://www.ebay.com/itm/Pair-Silicone-Arm-Cuffs-Orange-Standard/163638743726?epid=1849152843&hash=item2619a112ae:g:xZQAAOSwEvZcV0By - hose clip 100-120mm - Compressed air pistol which must be cleaned oxygen clean before use. https://de.aliexpress.com/item/1-st-cke-Luft-Blasen-Pistole-Pneumatische-Air-Linie-Ende-Komprimiert-Staub-Entfernung-Air-Duster-D/32963518244.html?spm=a2g0s.9042311.0.0.4fbf4c4dYuZuiM - Inflator nipple with 3/8" male thread https://de.aliexpress.com/item/1-st-ck-Scuba-Tauchen-Dive-Universal-BCD-Power-Inflator-Auftrieb-Kompensator-Kupfer-Nippel-f-r/32961311659.html?spm=a2g0s.9042311.0.0.4fbf4c4dYuZuiM - Storage box https://www.amazon.com/gp/product/B06XXD6FHC/ref=ppx_yo_dt_b_asin_title_o08__o00_s01?ie=UTF8&psc=1
