What our Experts Think
- The Go Power / Xantrex 12V → 115V inverter (X168133000UL) is a compact true sine wave inverter platform, designed for RV, marine, and mobile power systems where safe AC output is required for sensitive electronics.
- Delivers clean 115V AC from 12V DC, making it suitable for laptops, TVs, small appliances, CPAP machines, and entertainment systems without electrical noise or instability.
- Built around true sine wave output technology, ensuring compatibility with modern electronics and motor-based loads while reducing risk of overheating or performance issues.
- Designed for mobile installations (RV / trailer / truck systems) with emphasis on efficiency, low idle draw, and stable operation across varying battery conditions.
- Typically supports transfer-switch integration or remote control options, enabling seamless switching between shore power and battery power in RV setups.
- Includes built-in protection features such as overload, low-voltage shutdown, and thermal protection to safeguard both inverter and battery bank.
- Best suited for users needing a reliable mid-range inverter solution for RV comfort loads, rather than high-surge appliances like microwaves or heavy power tools.
Q&A
Q: What is the Dynabrade 6" DynaLocke Dual-Action Sander (58435) used for?
A: It is a professional 6-inch pneumatic dual-action (DA) air sander designed for fast material removal and fine finishing in automotive, metalworking, and composite surface prep.
Q: What makes the DynaLocke 58435 unique?
A: It features a dual-mode switch that lets you change between rotary disc sanding (aggressive cut) and random orbital sanding (smoother finish) in one tool.
Q: What are its main specs?
A: It runs about 12,000 RPM, uses a 6-inch hook-and-loop pad, and is powered by a 0.45 hp air motor with roughly 23 SCFM air consumption at 90 PSI.
Q: What materials can it be used on?
A: It’s commonly used on automotive paint stripping, body filler, metal panels, fiberglass, composites, and solid surfaces like Corian, making it a versatile shop tool.
Q: Is it vacuum compatible?
A: No, this specific model (58435) is a non-vacuum version, meaning it does not connect to dust extraction systems.
Maintenance Tips
- Lubricate air motor daily with pneumatic tool oil to maintain smooth 12,000 RPM performance.
- Keep compressed air clean and dry using a filter/regulator to prevent internal vane wear and rust.
- Inspect 6" hook-and-loop pad regularly for wear, imbalance, or loose attachment.
- Check air hose and 1/4" NPT fittings for leaks or pressure loss before each use.
- Clean dust and debris from housing and exhaust ports after every sanding session.
- Ensure correct air pressure (around 90 PSI) for optimal performance and motor longevity.
- Avoid prolonged heavy-load sanding without breaks to prevent overheating and reduced motor life.
- Periodically check throttle lever and recessed switch for smooth, safe operation.
- Store in a dry environment to prevent corrosion of internal rotary vane components
