GUN SAFE & FIREARM MOISTURE PROTECTION
Protect Your Firearms From Moisture, Rust & Corrosion
Looking for a simple gun safe dehumidifier Australiahas to offer? Damp Defender® Dehumidifier Rods help protect firearms, rifles, scopes, ammunition storage and shooting equipment from the damaging effects of excess humidity.
NO TANKS • NO CRYSTALS • NO RECHARGING
Damp Defender uses mild, continuous heat to warm, dry and circulate the air inside enclosed spaces, helping create an environment less favourable to moisture, rust, corrosion, mould, mildew and musty odours.
Simply plug it into an Australian 240V power outlet and leave it running.

Why Humidity Is a Problem for Gun Safes & Firearm Storage
A gun safe may look perfectly dry while still containing humid air. Every time the safe is opened, surrounding air enters — and as temperatures change, so does the relative humidity inside the enclosure.
For firearms, rifles, scopes, ammunition and other metal equipment stored for long periods, excess moisture can contribute to rust, corrosion, mould, mildew and musty odours.
This can be particularly important in Australia’s humid and coastal environments, including Queensland, Northern NSW, tropical regions and coastal areas throughout Australia.
Rather than collecting water, Damp Defender uses mild continuous heat to help warm, dry and circulate the air inside an enclosed space — with no tank to empty, crystals to replace or unit to recharge.
Which Damp Defender Size Do I Need?
Damp Defender is available in four sizes, making it easy to match the rod to your gun safe, firearm cabinet or other enclosed storage space.
