Compressed air for dust removal PRF 4‑44 405ml (300ml net) aerosol, flammable

Compressed air aerosol PRF 4‑44 in a 405 ml can (300 ml net) provides a focused, contact‑free air jet for removal of dust and loose debris from sensitive equipment. Intended for maintenance and periodic cleaning, the spray disperses a propellant stream that reaches narrow crevices in keyboards, cameras, printers, electronic boards and mechanical assemblies. The product is flammable; observe ventilation and ignition‑source precautions during use.

Advantages

This compressed air aerosol delivers a directed, high‑velocity airflow that dislodges dust without physical contact, reducing the risk of damage to delicate components. The compact aerosol can is lightweight and portable for use at workstations or in service kits. Using an aerosolized propellant allows access to tight spaces and layered assemblies where brushes or cloths cannot reach.

Suitable for

• Cleaning computer keyboards and laptop vents
• Removing dust from camera lenses and sensor housings (external surfaces and housings only)
• Blowing out dust from printer heads, paper paths and fans
• Maintenance of circuit boards, connectors and small mechanical parts
• Cleaning switches, relays and other electrical enclosures (with power off)

Key specifications

• Container volume: 405 ml gross, 300 ml net of propellant
• Form: aerosolized compressed gas for directed air jet
• Application method: short bursts to produce focused airflow
• Compatibility: suitable for non‑contact dust removal on electronics and precision mechanisms
• Safety class: flammable aerosol — observe ventilation and keep away from heat and open flame

How to use

Hold the can upright and use short controlled bursts to blow dust away from components. Maintain a safe distance from delicate surfaces to avoid cold‑shock or moisture condensation; start several centimetres away and adjust distance as needed. Keep the device powered off and, where possible, disconnect batteries or power cables before cleaning. Avoid prolonged continuous spraying to prevent cooling the can and causing propellant discharge or freezing of surfaces.

Usage recommendations

Use the aerosol in well‑ventilated areas and away from ignition sources. Store the can at room temperature and do not expose it to temperatures above those indicated on the package. After use, allow cleaned components to return to ambient temperature before powering on. Dispose of empty cans according to local hazardous waste regulations.
