Dusters 除尘剂

Dusters 除尘剂

Techspray dusters (commonly called "canned air", "compressed air", and "dusting gas") blow away dust, microscopic contaminants, lint, metallic oxide deposits and other soils that can damage sensitive electronics. When these contaminants get in the way of vents or fans within the device, they create a build up which leads to overheating and/or shortages. 

Techspray dusters do not contain additives that can contaminate sensitive electronics. Retail dusters generally have bitterant added to prevent huffing. This same bitterant can lead to unwanted and potentially harmful residues that can build up over time.

Choose the duster propellant that best meets your needs:

  • HFC-134a – Most common for industrial applications because it is nonflammable. Intended for cleaning energized circuits.
  • HFC-152a – Most commonly available duster in consumer retail because it is less expensive than HFC-134a. It is flammable, and will ignite when concentrated (i.e. in liquid form) and exposed to a spark or flame. 1/10th the global warming potential (GWP) of HFC-134a.

Techspray 除尘剂(通常被称为“罐装空气”,“压缩空气”和“除尘空气”)能有效吹除灰尘,细微污染物,棉绒,金属氧化物颗粒和其他可能损坏敏感电子元件的污垢。当这些污染物积聚在设备内的通风口或风扇上时,将导致设备过热和/或短路。

Techspray除尘剂不含有可能污染敏感电子元件的添加剂。市场上其他除尘剂通常含有苦味剂。随着时间的推移, 这种苦味剂的堆积会导致不必要的潜在有害残留物。


  • HFC-134a – 在工业中应用最为普遍。因其不可燃,常用于清洁带电电路。
  • HFC-152a - 零售中最常用的除尘剂,较HFC-134a便宜。当该除尘剂被压缩至液态并接触火花或火苗时可燃烧。仅为HFC-134a的全球变暖潜能值(GWP)的1/10。
