Industrial AL-40SB Linear Air Pump

Industrial AL-40SB Linear Air Pump is a compact, 12V DC pump that combines vacuum and pressure capability (SB) in a single, oil‑free package designed for continuous or intermittent duty in OEM equipment, lab instruments, aeration systems, and pneumatic benches. It delivers around 40 LPM of airflow with a rated pressure near 15 kPa, making it suitable for applications requiring steady, moderate flow. The unit features an aluminum alloy housing for durability, a discharge port with an outer diameter of 18 mm (approximately 0.71 in), and a quiet operating profile in the 36 dB range under typical load. Power is drawn from a 12V source at about 6A, aligning with automotive or off‑grid power sources. Built on ALITA’s oil‑free design, the AL-40SB provides contamination‑free airflow and a long service life, with thermal protection to guard against overheating in both indoor and outdoor installations. This model is marketed as a 12V, 40 LPM, SB (vacuum and pressure) variant, ideal for systems that require both suction and blowing capabilities without bulky equipment.
