11TF30SM

11TF30SM product function

11TF30SM is a fuel filter intended for use in the fuel system. Within the working circuit, it removes mechanical contamination from the fuel flow. Selection should be based on the complete designation because visually similar units can differ in flow capacity, working pressure, filtration rating, connections and internal configuration. This product is listed in the Aviamisto filters and filter elements category. Exact applicability to an aircraft, helicopter or ground installation must be confirmed from the illustrated parts catalog, system diagram or approved maintenance documentation rather than appearance alone.

Working medium and system position

The fuel filter is installed where the specified condition of the working medium has to be maintained and downstream components need protection or controlled flow. Contamination, excessive resistance or incorrect installation may affect pumps, valves, regulators and actuators positioned later in the circuit. For that reason, inspection covers more than the outer housing: internal elements, seals, connections and flow direction also matter. The working medium must not be selected by analogy. Only fluids or gases explicitly permitted by the product passport and system documentation should be used.

Operating data for 11TF30SM

Published technical data identify the following parameters: filter element designation — 340.146; filtration rating, nominal / absolute, µm — 16/25; working medium — aviafuel; nominal working pressure, MPa / kgf/cm² — 0.3 (3); maximum flow capacity, L/min — 10; hydraulic resistance, MPa / kgf/cm² — 0.015 (0.15). These values have to be considered together. A matching pressure rating does not confirm the required flow, and a similar envelope does not guarantee the correct filtration grade or valve setting. During incoming inspection, the marking and passport are compared with the removed unit and the applicable maintenance data. Numerical specifications from another modification should not be transferred automatically to 11TF30SM, even when the housings appear identical.

Construction and associated components

The available description identifies regenerable filter media, bypass valve, drain provision. The condition of associated parts affects the entire line: a contaminated element, damaged seal or faulty valve can produce symptoms that resemble failure of the principal unit. Directly related items include 340.146. They belong to the same functional chain but are not treated as interchangeable without documentation. Related catalog positions include 11TF30SM-0, 11TF30M, 11TF30SM-1, 12TF15. They are shown for catalog navigation and are not claimed to be interchangeable. Maintenance checks normally cover channel cleanliness, threads and fittings, corrosion or impact damage, and the delivery set required by the technical request. Service procedures for washable or regenerable media must follow the approved documentation.

Identification and ordering

Requests should state 11TF30SM, the system, installation position, required condition and documentation set. A clear photograph of the removed unit's nameplate can help identification, but visual similarity alone is not a sufficient basis for replacement. Before installation, compare the passport, drawing or parts catalog, permitted working medium, connection geometry and principal ratings. Supply is handled on a pre-order basis; actual configuration, lead time and availability of a passport, test record or other supporting documentation should be agreed before the order is confirmed.
