- Fits Bourns/Bear, Bennet, Siemens, most ventilators.
- Use on inhalation side only, do not use on exhalation side.
- Guaranteed 25 cleanings without flow resistance tests.
- High efficiency, particulate air (HEPA)filter
- 99.97% filtration efficacy of 0.3 micron or larger.
Do not place filter downstream of a humidification system. Increased resistance to flow may develop.
Do not place the filter in the path of nebulizer output. The filter will trap the aerosol, and the buildup of resistance will shorten the life of the filter.
Make sure sterilization procedure includes a drying cycle.
Connect the main flow filter inlet to the ventilator outlet, observing at all times the flow direction arrow. Our filters are clinically efficatious with most ventilators and their respective installation directions can be used for installation of our filter.
Besides care during handling and sterilization,
maintenance is limited to replacement of a filter when it becomes
so loaded with particles that it offers too great a resistance to gas
flow. However, even this maintenance is minimized because there are 25 cleaning boxes molded into the filter housing, which should be scribed or marked before each autoclaving. The flow resistance tests will not be required until the 25th box has been marked. If flow resistance tests become necessary, the filter should be replaced when the pressure drop accross the filter exceeds 4.0 cm H2O at 100 LPM flow.

Mark each use with permanent marking pen.
Use # 1469 reusable coupler where coupler is required.
