4240294 HITACHI Air Filter – Precision Air Filtration

The HITACHI 4240294 is a high-performance primary air filter specially designed for HITACHI construction machinery, including excavators like the EX700, EX800 – 5, EX1200 – 6, and ZX 450 – 3 LC 3 Zaxis series. It also fits some Kawasaki equipment and Cummins NTA855 – C450 engines, serving as a core component for engine air intake systems to provide precision air filtration in dusty and harsh construction sites.

It achieves a 99.9% filtration efficiency as tested by the ISO 5011 standard, capturing tiny dust particles and solid contaminants in the intake air. This prevents abrasive wear to engine cylinders, pistons, and other key components, avoiding issues such as reduced compression efficiency, power loss, and premature engine failure caused by contaminated air intake.

Crafted with high-quality cellulose filtration media, the filter features a round structural design that maximizes the filtration area. It has precise dimensions: an outer diameter of 307.2mm, an inner diameter of 196.2mm, and an overall length of 622.3mm, with a 22.61mm bolt hole diameter. This optimized structure balances efficient contaminant blocking with smooth air flow, ensuring the engine gets a sufficient air supply to maintain optimal combustion efficiency and fuel economy.

Made of heavy-duty high-quality steel and durable filter paper, along with reliable adhesive materials, it can withstand the strong vibration of construction machinery during operation and extreme temperature changes on construction sites. It maintains stable and reliable filtration performance for over 3000 hours of service life, adapting to long-term high-intensity working conditions.

More than just an air filter, it is a critical engine protection barrier for HITACHI construction machinery. It extends the engine’s service life, reduces maintenance costs and downtime, and upholds HITACHI’s rigorous quality standards for construction equipment parts.
