GVS air vents are manufactured with fully automatic over-molding technology that guarantees superior quality in manufacturing parts with high cavity molds.
There are several models listed below that typically enable customers to find a suitable product for the intended application.Our wide range of available media (PTFE and acrylic membranes) provides high flexibility and covers most market requirements. Because of our wide choice of pore sizes and varying filter media, it is possible that the GVS air vents will be compatible with an existing or new device. Available are membrane sizes are from 0.02 to 10 micron.
Because we use many ddifferent raw materials for the frames and/or housings of our products, it is possible to choose assembly methods of mechanical sealing (interference fit) or bonding (standard with cyclohexanone, methyl cyanoacrylate or methyl ethyl ketone). Available air vents have female luer locks or male luer slip connectors
Air elimination is an important feature for an air vents. .Customers always require small vents with very fast air elimination performance. Air elimination really depends on the effective filtration area and on the pore size of the membrane used. Air Flow is one of the key characteristics that should be considered when choosing an air vent.
Bacteria and/or fungi can create patient contamination. These unwanted contaminants cause phlebitis and infections. Our air vents are an ideal barrier to this contamination guarding against bacteria and fungi reaching the fluid path, and eventually the patient. Although no one should knowingly use a contaminated solution, our air vent equipped with membranes are bacterial retentive. ForFor bacterial retention consideration, always keep in mind that filtering bacteria in air is about 10 times more efficient than in water, which means that this enables hydrophobic membranes of 1.2 or 3 micron to filter Brevundimonas diminuta (0.2µm by a hydrophilic membrane in liquid).
GVS air vents comply with the ISO 10993 standard for external communicating devices - blood path indirect - prolonged contact duration.
Our air vents have low protein binding characteristics that ensure minimal adsorption of drugs, and they have proven bacterial retention. Drug compatibility depends on the membrane used.
