GUANLIN RTO inlet pre-filter, G4 primary panel set protecting regenerative thermal oxidiser media beds.
G4 primary efficiency pre-filter sets installed ahead of RTO and RCO media beds, removing coarse particulate that would otherwise foul the ceramic heat exchange media.
Description
Ceramic heat exchange media is expensive and difficult to clean once fouled. Coarse particulate that reaches the RTO bed deposits in the channels, raises pressure drop permanently, and in severe cases blinds whole sections. A G4 pre-filter upstream is the cheapest insurance in the whole system — it costs a fraction of what media replacement or bed cleaning costs.
Why Choose GUANLIN RTO Inlet Pre-Filters
- Protects ceramic media — removes coarse particulate before it enters the bed channels.
- Keeps pressure drop stable — fouled media raises RTO fan load permanently.
- G4 efficiency — appropriate for the coarse fraction without excessive resistance.
- Matched frames — panel and holding frame supplied as a set with no edge bypass.
- Simple changeout — the whole stage swaps in one operation.
- Custom sizes — to your RTO inlet plenum.

FAQ
Q1. Why pre-filter an RTO?
Coarse particulate fouls the ceramic media and raises pressure drop permanently.
Q2. Is G4 enough?
For coarse dust yes; a medium stage may be added for fine particulate.
Q3. Can it handle hot gas?
Standard panels suit ambient to 80°C; hot gas needs high temperature media.
Q4. MOQ and lead time?
20 sets, 10–20 days.
