Spare Parts for GE Engström and R860 Ventilators: Flow Sensor and Valves

GE Engström and R860 ventilator: flow sensor 1505-3208-000, MPOS valve 1505-3209-000-S, exhalation valve 1505-3848-000, board 1505-5508-000 and oxygen filter.

The gas path of a ventilator is the part of the station that runs continuously and wears out on a consumable schedule. The flow sensor, the flow control valve and the oxygen filter are quickly replaceable items: they are changed as routine, without complex repair, but only if the assembly is in stock. That is precisely why the GE Engström and R860 ventilator fleet is easier to service from a pre-built reserve of specific PNs, rather than on a failure-by-failure basis in the middle of a shift in an intensive care unit.

This guide covers six items that have entered the MediAccessori catalog for GE ventilators: a flow sensor, flow control and exhalation valves, a breathing circuit diaphragm valve, an interface board and a high-pressure oxygen filter. For each item the official catalog description, compatible equipment, an approximate price in rubles and stock availability are given, and at the end there is a summary compatibility matrix and a review of typical faults.

1. Why the ventilator gas path needs a dedicated reserve

A ventilator has two groups of failures. The first is related to electronics and software, the second to the gas path: flow sensors, valves, filters and the breathing circuit. The second group occurs more often, because these assemblies are in constant contact with gas flow and moisture.

The practical conclusion for a service department: keep one or two items of each class in stock — sensor, valve, filter, board. Then replacement takes hours rather than weeks of waiting for delivery.

The distribution across machines should also be taken into account: some items in the selection are tied to Engström, others to R860. Before purchasing, compare the compatibility section of the card with the model of the specific station.

2. 160L flow sensor: PN 1505-3208-000

Official catalog description: Breathing Circuit Gas (BCG) flow (0–160 L/min, LPM: 0–160) — electromechanical sensor block.

Equipment: Engstrom (ventilator) · Approximate price: 52,800 ₽ · Availability: 1 pc.

The respiratory flow sensor is a consumable element of the circuit: the machine uses its readings to calculate tidal volume and control ventilation. The electromechanical sensor block belongs to the wear parts, so it is replaced as routine rather than repaired.

Note the availability: 1 pc. in stock means the item should be reserved for a specific machine in advance. If a department has several Engström stations, it is sensible to order the sensor before a failure occurs, not at the moment it does.

3. Valves: flow control and exhalation valve

PN 1505-3209-000-S — 160 LPM flow control valve (MPOS)

Official catalog description: 160 LPM flow control valve for medium pressure oxygen (MPOS).

Equipment: Engstrom (ventilator) · Approximate price: 143,000 ₽ · Availability: 2 pcs.

The flow control valve operates in the medium pressure oxygen circuit and determines gas delivery accuracy. Signs of wear — unstable flow, a discrepancy between commanded and actual ventilation parameters, calibration errors.

This is the most expensive item in the selection (143,000 ₽), so its purchasing logic differs from consumables: the valve is purchased into the service department's stock, one assembly per group of machines.

PN 1505-3848-000 — exhalation valve (with flow sensor)

Official catalog description (English): EVA + Flow Sensor

Equipment: R860 (ventilator) · Approximate price: 49,500 ₽ · Availability: 20 pcs.

This item combines the exhalation valve and the flow sensor in a single assembly. Availability of 20 pcs. at a price of 49,500 ₽ makes it the most convenient candidate for permanent reserve for the R860 fleet: replacing the exhalation valve is routine work, and downtime of a ventilator station costs more than the assembly itself.

4. BCG diaphragm exhalation valve: PN 1505-3224-000-S

Equipment: R860 (ventilator) · Approximate price: 7,260 ₽ · Availability: 5 pcs.

No official catalog description is provided; the item name states the purpose — BCG diaphragm exhalation valve for the breathing circuit.

The diaphragm valve belongs to the consumable elements of the circuit: the diaphragm works in the inspiration and expiration cycle, so its wear shows up as unstable circuit tightness and a discrepancy in ventilation parameters. At a price of 7,260 ₽ the item is convenient to keep in reserve together with the exhalation valve.

5. Electronics: interface board 1505-5508-000

Official catalog description: not provided; the card states the purpose — interface board.

Equipment: GE R860 · Approximate price: 10,780 ₽ · Availability: 5 pcs.

The board belongs to the ventilator's electronics: it provides data exchange within the station. If the machine reports interface errors or does not reach operating mode after power-up, troubleshooting usually starts with the board and its connectors.

Since no official description is provided for the item, clarify the installation location and revision against the service documentation of the specific machine.

6. High-pressure oxygen filter: PN 1505-3060-000

Official catalog description: not provided; the item name states the purpose — high-pressure oxygen filter.

Equipment: Engstrom (ventilator) · Approximate price: 2,750 ₽ · Availability: 20 pcs.

The filter protects the gas path from contaminants and belongs to scheduled consumables. It is the most affordable item in the selection: at a price of 2,750 ₽ and with 20 pcs. in stock, the filter logically belongs in permanent reserve and in the scheduled maintenance plan, rather than being ordered after a failure.

8. Typical faults and diagnostic sequence

  • •A discrepancy between commanded and actual flow, calibration errors — check the flow control valve (1505-3209-000-S) and the flow sensor (1505-3208-000).
  • •Unstable tidal volume, false flow alarms — check the respiratory flow sensor (1505-3208-000).
  • •Circuit leakage, unstable expiratory parameters — check the exhalation valve with flow sensor (1505-3848-000) and the BCG diaphragm valve (1505-3224-000-S).
  • •Interface errors, the station does not reach operating mode — check the interface board (1505-5508-000).
  • •Pressure drop in the oxygen supply line, contamination of the path — check the high-pressure oxygen filter (1505-3060-000).

The diagnostic order is from cheap to expensive: filter, diaphragm valve, flow sensor, exhalation valve, interface board, flow control valve. This order makes it possible to avoid replacing an expensive assembly if the cause was a consumable.

9. How to plan the purchase and the reserve

A practical annual plan scheme for a department with GE ventilators:

  • •permanent consumables reserve — oxygen filter 1505-3060-000 (2,750 ₽, 20 pcs.) and BCG diaphragm valve 1505-3224-000-S (7,260 ₽, 5 pcs.);
  • •reserve for the R860 fleet — exhalation valve with flow sensor 1505-3848-000 (49,500 ₽, 20 pcs.) and interface board 1505-5508-000 (10,780 ₽, 5 pcs.);
  • •items for a specific machine — flow sensor 1505-3208-000 (52,800 ₽, 1 pc.), reserved in advance because of limited availability;
  • •reserve for a group of machines — flow control valve 1505-3209-000-S (143,000 ₽, 2 pcs.).
