The Vanguard 120 series was created as a cost-effective solution to protect one or two critical electronic devices with the same circuit and performance as our larger products.  We achieved that with the Vanguard 120 series.  Designed, engineered and manufactured in the USA (Whitewater, Wisconsin) using domestic and globally-sourced components, the Vanguard 120 will do its job of filtration, power factor correction and surge suppression on all three wires for decades.  These units carry a five year no-fault warranty.

Our professional-grade power conditioning with superior surge protection is for business and home office professionals whose livelihood and reputation depend on high quality, high performance systems that demand safe, clean power. This is not a consumer-grade surge protector to (sort-of) protect your inexpensive electronics. Bantam Clean Power's Vanguard series features patented technology that provides true Power Conditioning, which is defined as Complete Surge Suppression, EMI/RFI Filtering, Stable Ground Reference, Power Factor Correction, Harmonic and Noise Attenuation and Bi-directional Protection. The Vanguard series is a product you can trust; it is protecting critical systems worldwide and has been for over fifteen years. All these features are inseparably part of the same cost-effective, space-efficient package.

These units are in use throughout the world in restaurants, sporting and concert venues protecting some of the most critical equipment like handheld device charging stations, wireless access points, temperature and motion monitoring sensors and surveillance cameras.  They have proven themselves for over fifteen years in the market.

Why Should You Buy the Vanguard 120?

  • Industry-leading surge suppression protection for small but critical devices (POS, card readers, scanners, thermal printers, iPad terminals, etc.)
  • Uses virtually no power (not transformer-based)
  • Two standard NEMA 5-15 receptacles, widely spaced to allow for power bricks and odd-shaped plugs
  • Designed, Engineered and Manufactured in the USA (Illinois and Wisconsin)
  • Perfect for your home, office, garage, shop or bunker.
  • A single phase power conditioner and Surge Protective Device (SPD)
  • Features harmonics filtration and power factor correction.
  • This SPD prevents “surge coupling” across all wires with its patented circuit
  • It is intended for installation closest to the point of use.
