Blauberg UK 6" 150mm 90 Degree Bend for Ventilation, Extractor Inline Fans Ducting

As with most portable air conditioners, mine has a single 150mm duct that leads to outside air coming back in to replace what's vented. In a crude method to add a second 150mm duct, I needed a 90 degree pipe bend to reach out the window (i.e. this item) and a cardboard box with a circular cut-out to feed the duct to the air conditioner's lower inlet.This 150mm bend fits snug over one spiral of the 150mm duct as shown in the image. To prevent it sliding off, I just applied a few pieces of masking tape around the duct spiral to this bend. For the window, I cut out a piece of cardboard the width of the window and a circular cut-out to fit this 90 degree bend and the original air conditioner's duct end into. In addition to the now balanced airflow, this minimises outside air getting in when it's breezy outside.

This elbow was, although 6" diameter, it would not fit inside or outside the concertina tube. I made an adapter from a large coffee tub ( 6 1/8" diameter) and 'gaffer taped it together. The elbow fitted inside the outside ducting and inside the coffee tub. I would have thought that the elbow and tube would have been a standard fit. -One slightly smaller than the other ---They were exactly the same size!

Very sturdy

Great price, great product, fast delivery, only comment would be that either these tubes are slightly larger than 150mm or the 90degree bends are slightly smaller as they are not a snug fit.

this helped with the ducting from our recently purchased air conditioner.

Excellent service quick delivery also product is very good quality.--Thanks

Does the job.
