Berd-Air comparison

[BeeAmaker]

10mm tube
PLA 205c spiral vase
The one on the right was printed without any cooling at all.
The one on the Left, printed at 75% Berd-Air cooling.
You can see at the bottom of the left tube, I started out at about 30% cooling, then increased it until the tube printed correctly.

Looks great.
I finally made a ring this week and am looking forward to trying it out.
The 3 straight air pipes with the big pump was hard to direct air just where needed on part. Turned up very high it would cool hot end way to much... about 20c drop very quick and it can't recover.

What size and how many holes do you drill in your rings?

Mine has 9, 1mm holes.

I recently installed the berd air max and found that the ring around the nozzle is blowing really hot air. The second straight nozzle will blow cold air. The pump motor is on top of my 3d printer (rostock max v2) and the vent holes are not blocked. Is the hot air normal or should I be getting cool air from both nozzles?

Also this is my first time using a product like this, previous i had three fans installed. So I noticed that not only the hot air from the nozzle ring but the air flow isn't a solid flow, it's like really fast puffs of air (that's how it sounds sorry for a bad description). Anything above 85% fan speed will provide a consistent solid flow of air, below that it's as described above. Is that normal?

Make sure the ring isn't touching the heater block. It is aluminum and will absorb the heat from the heater black very quickly.
If you are using the E3D hotend, I recommend getting the silicone sock they sell for insulation. If you look at the picture above, mine is very close, but not touching the heat block. In either case, moving air is more important than warm or cool air.
Also note that if the ring is against the heater block, it will inadvertently cool your nozzle as well.

The puffing sound is a result of this style of pump, at slower speeds you may notice a puff of air instead of a steady steam. I have found that to be a non-issue.

Thank you for such a quick reply! I am using a e3d v6 hot end and I don't have the sock. Though I made sure that the cooling ring is not touching the block or the nozzle. I have noticed that it really does absorb the heat.
I'll order a sock and give it a shot.

I think the sock only fits the newer block that uses the cartridge style thermistor.

You are correct! I had to order the new block after I got the socks not realizing the size difference between the two blocks. Either way I have installed the new block and sock and ran some tests... Unfortunately I am still getting really really hot air blowing out on the part. I'm struggling printing some overhangs that I used to be able to print when I using my three fan setup. To note - I am only using the ring for cooling, unfortunately the straight tube broke shortly after installing it, I was attempting to adjust the angle and well it broke in half. Haven't ordered a replacement yet. Ill try to upload a picture of the part to show where I'm having trouble if it helps at all.

Pull the hose off the tube, are you getting hot air out of the hose?

JUST SIGNED UP to this forum as i bought the berd air system.how does the motor connect to the board?do i use the pwm fan output of my mks 1.4,the one the normal layer fan used?

You can as long as the Fan output can handle at least 1 amp. I'm not familiar with the MKS 1.4, perhaps someone else here is.
Who manufactures the board, do you know?
