Airflow Faulty Product Returns Process

One of the reasons we have been selling Airflow products for so many years is that we have very few returns and of those probably 90% of the items returned are not faulty – they were just installed incorrectly.

Should you be having any issues with the installation of your Airflow product please call customer services on 01494 525252.

Any product considered to be faulty must be registered with Airflow first, who will go through a basic fault finding process to determine if the item needs further investigation and issue a PID number.

Only faulty products with a PID number can be returned to MailHeat; this does not guarantee a credit or replacement – this will be decided by Airflow after testing said item. If returned without a PID number repatriation postage would be at a cost to the sender.

What is most likely to invalidate my 3 year warranty:-

Any modification immediately invalidates warranty

Removal of the Airflow data badge

Insufficient cleaning and/or maintenance 


AIRFLOW 72687102 PIR / HUMIDITY / TIMER MODULE


Motion sensor activation with adjustable humidity setting between 40-90% RH, and adjustable timer between 1-30 Minutes.


I send these out of the box as it reduces it from a parcel to a large letter and that saves £2.50 on postage which I pass on. 

 This DOES NOT affect your 3 year warranty in any way. 


Please note:

Plastic adjustment tool must be used DO NOT use a normal screwdriver electrical or otherwise.
