Do you need extra ventilation power for your CO2 laser engraver? 

OMTech's inline duct fan keeps your machine and workshop as fresh as a daisy. Designed for 4"/6" ducts, this ventilation and exhaust fan eliminates odors and keeps your environment habitable thanks to its 2500 rpm rotational speed and 200 cfm airflow. While the sturdy base and aerodynamically designed impeller ensure smooth operation, it works quietly under 50 dB even on high with the help of added PVC cover which further muffles any sound and vibration. The galvanized steel casing, PVC cover, and PA66 blades offer durable service and corrosion-proof performance in laser engraving machine workshops. The external speed controller allows granular control of the fan's speed to meet your needs. Install it in only a few minutes at the height you find most suitable thanks to its intuitive design and clear instructions.

Great product!

Good but if the elastic band were wider it would be great
Color: Black
This is a great under helmet or perspiration barrier for the face during heavy spinning workouts. Sadly to avoid an indentation to your forehead, you must wear it inside out because the sewing band is narrow and tight.

Too damn small
Color: Black
Way too small for an adult. It doesn't even fit my 11 year old. Unfortunately I didn't open it immediately or I would have returned it. Now I'm stuck with something nobody in my house can use.

One size definitely doesn’t fit. Otherwise Ok.
Color: Black
OSFM - one size fits most. It should be OSFS - one size fits small/some. Measured my head size and according to their chart I’m l/XL. This cap is tight fitting and gives you a headache after an hour. Otherwise it’s fine. Keeps your head cool, is absorbent and works well under a helmet.
