Either

which has the air supply in the base
or

http://www.aliexpress.com/item/Rework-Station-SAIKE-8310D-220v-or-110v-soldering-station-hot-air-station-soldering-iron-Preheat-station/32365252322.html

which has an integral preheat (but maybe not so good on the hot air gun!!)

or another brand and what characteristics should it have?
