SEV551A/4 Primary Air Filter for Perkins 4016 Series Engines
Сайт СЕВ551А/4 is a long-body primary air filter designed for Perkins 4016 diesel generator sets, widely used in large continuous-duty power plants.
In our Bowei filter factory we manufacture this model in full production — from media pleating to iron-cap forming — ensuring stable airflow and long service life.
Factory Manufacturing (How We Build SEV551A/4)
• Ahlstrom wood-pulp blended filter media, folded on our fully-automatic pleating machine for consistent pleat spacing
• Precision-formed iron end caps with high-temperature adhesive
• Outer mesh rolled and locked on an auto-wrapping line to maintain roundness on long 800 mm bodies
• Each filter is tested for pressure drop, airflow uniformity, and sealing strength
• Final QC performs 3-point measurement (OD/ID/Length) on every batch
• Large filtration surface area provides стабильный поток воздуха even under continuous heavy load
• Ahlstrom media keeps restriction low and ensures высокая пылеемкость
• Iron end caps prevent deformation in high-temperature generator rooms
• Designed for long service intervals in 24/7 base-load generator operation
