The Sealey MAC13D is a dual-power (12V DC and 230V AC) tyre inflator and high-volume air pump. It features an auto-shut-off function when the pre-set pressure is reached, a digital display, and an integrated LED worklight. Always monitor the pressure gauge during operation and avoid continuous use for more than 15 minutes to prevent overheating; a 10-minute rest period is recommended.
