Product Information

A fan guard protects your PCB by preventing dust and water ingress. Materials vary when it comes to fan parts, and that goes for fan guards. For instance, you can get a plastic or a metal fan guard. Your choice will probably depend on the look and strength you’re after, and which option fits your budget. A metal fan guardis installed with a screw-mount application. Plastic is a bit more versatile. For example, you can get a plastic fan guard with a screw-mount applicationor one that snaps in. So what exactly is the difference? Spacers are unthreaded, with a through hole. Standoffs are threaded on both ends and come in both male and female designs. Sometimes you’ll see the description “threaded round spacer”. This is a standoff, because it’s threaded. The bottom line is, they have the same purpose. The difference is in whether or not they’re threaded. Melt temperature of 100˚C - 260°C (212˚F to 500°F), heat deflection temperature of 92°C (198°F) and tensile strength of 1,000 to 3,625 psi (Flexible PVC) / 4,930 to 9,000 psi (Rigid PVC). Some of its weaknesses can be offset by copolymerisation with other monomers. For example, it can be copolymerised with ABS, giving it high stress and impact resistance and higher tensile strength.

Impact-Modified Nylon: extremely high-impact strength at low temperatures and resistance to heat distortion, compared to Nylon 6/6. Mounts help position and secure your fan. You can even get anti-vibration rubber fan mounts to reduce noise generated by the fan. These type of fan mountsare usually made out of an elastomer, such as silicone rubber or Acrylonitrile-Butadiene-Styrene (ABS). Rubber Grommets: Usually made from thermoplastic rubber and EPDM and are typically used to protect wires and hoses from abrasion and damage.Materials vary. Use ceramic spacers for extremely high-temperature applications. PCB plastic spacers, such as a Nylon PCB standoff, offer good corrosion resistance and are cost-effective for mass production, while still having good mechanical properties. They’re also the preferred choice over metal if you need a lightweight alternative. Different types of grommets can offer specific benefits depending on the usability and working conditions, such as electrical wire protectors (EWPs), IP54 sealing, and high-heat resistance. They are widely used in various industries, including data centres, telecom and automotive industries and manufacturing facilities.

For your convenience, you can also get fan filter sets, which provide you with a finger guard, filter cover, mesh filter and felt filter. They are commonly used in home and office furniture, computer desks, and audio/visual equipment. Grommet Accessories Glass-Filled Nylon: gives materials tensile strengths of up to 32,000 psi, which is around 200% higher than the base resin. Also, heat deflection temperatures increase from 75˚C to 130˚C (185˚F to 266˚F). Poor heat stability, which is why additives are put in during manufacturing. This helps stabilise the material at higher temperatures.Heat-Stabilised Nylon: shares the same mechanical properties as Nylon 6/6, but also has the advantage of heat stabilisation. Stand up to 125˚C (257˚F) temperatures. Fans are your best option for your PCB’s heat management. To enhance your fan’s safety and efficiency, you’ll need the right parts.
