Seed Ventilation System The Seed Ventilation System keeps seed fresh longer!
The Squirrel Buster Classic features Brome's patented Seed Ventilation System. Most seed tubes act like a greenhouse; they trap the energy from the sun. Warm, moist air that has been heated by the sun causes bird seed to spoil faster. To prevent this problem, Brome's Seed Ventilation System allows hot air to escape from waterproof vents on the top of the feeder. Fresh air enters the feeder from the seed ports and openings on the seed tube. This flow of air allows the seed to remain fresher. In turn, this will attract more birds. This also helps to ensure that the birds that visit your feeder are safe. Dirty feeders and spoiled seed are a hazard for the birds that visit your yard. Keep your seed fresh with the Squirrel Buster Classic.
