ar2explosion is a point entity present in some Source games. It's the actual dust cloud generated by an env_ar2explosion. It's advised to not spawn these directly as they will not be removed automatically after the dust fully dissipates and will artificially increase the entity count. env_ar2explosion also gives more control over the dust cloud. You can still do some things to this entity such as Killing, to immediately remove sprites.
