Transaction Drawers

Pass-through transaction drawers for drive-up windows, teller lines, and service counters.

Frequently Asked Questions

What's the difference between drive-up and point-to-point pneumatic tube systems?

Drive-up systems serve customer-facing transactions: a customer pulls up to the unit, sends or receives a carrier, and the carrier moves between the customer position and an operator inside the building. Point-to-point systems move documents between two operator stations. Comco’s 450FI, 522, 523, 621, 901AX, and 921 are drive-up systems. The EZY Flo is point-to-point.

What's the difference between 4-inch and 4.5-inch tube systems?

The 4-inch tube is the older standard, still common in many installations. The 4.5-inch tube is the more modern standard, with larger carriers that handle more items per send. Comco offers both sizes across most product lines. [Comco to confirm which specific models offer which sizes.]

How loud is a Comco pneumatic tube system?

Operating noise is similar to a typical office printer cycle. Send and receive events are audible but not disruptive. Customers and staff rarely cite noise as an issue in Comco installations.

Can I retrofit a Comco system into an existing structure built for another manufacturer?

Often yes. Rough-in dimensions for every Comco product are in the cut sheet and CAD block. Comco’s engineering team can review existing drawings to confirm fit before quote. Many customers retrofit Comco equipment into structures originally built for other manufacturers.

How long does install take?

Project-specific. Single-position drive-up installs are quicker than multi-lane setups. Hospital and industrial point-to-point installs depend on tube routing and site coordination. Comco’s project manager scopes the timeline during design, before equipment ships.

Does Comco service competitor systems?

Yes. Comco’s service network covers all major pneumatic tube and drive-thru brands across all 50 states. If you have a non-Comco system, we can service it.
