If a unit gets recalled to base does any equipment attached get detached?

No, when a unit is recalled to your base, any attached equipment remains attached to it.

According to the RiftJudge FAQ (ID 8698):

• The unit moves from the battlefield to the base (both are board zones).
• Gear stays attached throughout the recall.
• The unit arrives at the base with gear still attached.

Gear only detaches when a unit moves from a board zone to a non-board zone (such as being destroyed, banished, or returned to hand). Since a recall is a board-zone-to-board-zone movement, the attachment is maintained.
