Key Features & Benefits

• No-rinse, ready-to-use aerosol (18 oz / ~532 mL, part no. 4166-75) → Faster services with less mess and water on site.

• EPA-registered hospital-use disinfectant → Proven kill claims to back up hygiene jobs in sensitive sites.

• Foaming action clings to fins → Better dwell & penetration through tight evaporator packs for a cleaner coil.

• Non-abrasive, aluminium-safe formula → Protects delicate fins & coatings, reducing damage risk and call-backs.

• Fast dwell (3-minute disinfection; up to 10 minutes for specific viruses) → Speed on routine cleans; still covers tougher protocols when required.

Why This Product Matters

If you’ve ever been on a sticky Brisbane arvo, head jammed inside a cassette, juggling pump sprayers and rinse bottles—you’ll know rinse cycles chew time. Evap-Fresh goes on, disinfects, and air-dries. That’s a ripper when you’re knocking over multiple split services on a tight schedule.

Pro Tip

Disconnect power and let the coil surface come to room temp before spraying. Keep the surface visibly wet for the required contact time (most disinfection jobs: ~3 minutes; certain viruses require longer—check the label/SDS). Use only as directed and follow local chemical-handling rules—too easy.
