K-40

K-40 Two-Stage Pump The K-40 combines high-volume and high-pressure stages for efficient inflation and topping off. Shorter and lighter than the K-400, it produces over 70% of the K-400’s volume while taking up less space. Perfect for AIRE rafts, this pump is rugged enough to lash into your rig-to-flip setup and compact enough to carry on the river. A favorite of guides and outfitters, it’s built to last and comes with a travel bag for secure storage.
