Radial Seal Architecture

AF1855 Air Filter

AF1855 Air Filter features an advanced heavy-duty radial seal architecture tailored for severe operational dust loads. Boasting an external diameter of 150.0 mm and an extended profile height of 380.0 mm, this structurally reinforced canister utilizes deep-pleat media distribution to maximize particulate containment while maintaining low restrictive intake values. The rugged outer wire netting guards against high-vibration structural collapse under intense suction pressure. This critical engine component delivers long-term technical protection across major agricultural and industrial equipment segments, offering drop-in installation for an expansive range of FORD AGRI legacy tractors (including 2310, 2600, 3600, 4600, 4610, 5030, and 6600 systems). Additionally, it ensures clean air delivery metrics for FARMTRAC 535, 550, 675 FT, and 80 FT power setups, as well as CECCATO and COMPAIR-HOLMAN RA 40 and RA 60 mechanical air installations.

AF1855 Product Frequently Asked Questions (FAQ)

Q1: Can the AF1855 Air Filter replace the Donaldson P526505 directly without modifications?

A1: Yes, this element is a 100% direct dimensional interchange. It meets identical radial parameters (D1=150.0 mm, H1=380.0 mm) to fit standard factory housings with zero modifications.

Q2: Which specific tractor models are primarily served by this filter?

A2: It provides extensive application coverage for older agricultural fleets, specifically maximizing performance across Ford Agri 2600 through 6600 series and Farmtrac 535/675 models.

Q3: How often should this element be checked or replaced in high-dust agricultural zones?

A3: It should be inspected every 50 to 100 operating hours in dusty field work. Full replacement is recommended at 250 hours or whenever the cabin restriction indicator lights up.

Q4: What happens if raw bypass air passes the inner D3 seal area?

A4: Any seal failure around the 78.0 mm inner diameter allows raw dust to bypass the filtration media, which can cause severe abrasive cylinder wall scoring and accelerated engine wear.

Q5: Is this a washable filter element that can be reused?

A5: No, this uses high-efficiency cellulose pleats. Attempting to wash or spray it with fluids will ruin the paper matrix pore structure, completely degrading its micron rating and dust-holding capacity.
