Mae hofrenyddion mewn perygl o gael eu difrodi gan dywod, rhew, lleithder a gwres. Mae Air Covers wedi datblygu cynnyrch i warchod rhag y peryglon hyn, a fyddai fel arall yn cwtogi yr amser y maent yn gallu bod yn yr aer.  Mae'r gorchuddion hefyd yn lleihau yr angen am waith cynnal a chadw, a allai yn ystod oes awyren neu hofrennydd fod deirgwaith pris prynu yr hofrennydd gwreiddiol.
Helicopters are vulnerable to environmental damage from sand, ice, humidity and heat. Air Covers have developed products to protect against these hazards which would otherwise reduce operational time in the air.  The covers also reduce the need for maintenance, which over the lifetime of an aircraft can easily be three times the purchase price of the original helicopter.
